Implantation Bleeding or Period? Quiz

For fertilization to occur, fusion of an egg and sperm must occur in the female reproductive tract. This usually happens in the fallopian tube. Once the egg is fertilized, it travels down the fallopian tube and attaches to the lining of the uterus. When it attaches here, some blood vessels are ruptured and the lining of the uterus is disrupted. This causes symptoms of light bleeding and cramping.

Uterus - Implantation bleeding

This is known as "implantation bleeding" - discharge that occurs due to the implantation of the fertilized egg into the uterine wall. It is the first sign of pregnancy.



How do I know it isn't just my period?

1. Timing

If you experience spotting before your period is due to begin, this may be due to implantation bleeding. The timing of the bleeding depends on the length of your cycle and when and where fertilization occurred. It can occur anywhere from a week to the day before your period is due to begin.

2. Duration

Your normal period may last from three days to a week, but implantation bleeding usually occurs for less than two days. Some women may only see the spotting or light discharge on one day or for a few hours.

3. Color

Implantation bleeding is normally a pinkish or brown colored discharge rather than the sharp, red color of a normal menstrual period. There is no change in the color through the duration of the spotting.

4. Quantity

Where during a normal period you may need to change a tampon or pad once every four-five hours, implantation bleeding is generally a few drops and very light in quantity.

5. Other symptoms

The symptoms you might expect from your normal period such as acne, mood swings and painful cramps do not usually occur with implantation bleeding. You may find light abdominal cramping which is completely normal, but the other hormonal impacts of menstruation do not occur in implantation bleeding.

6. Basal Body Temperature

Basal body temperature is the lowest resting temperature of your body, usually at rest. Immediately following ovulation, BBT increases and stays elevated until the next period. If you are monitoring your BBT for ovulatory purposes, in implantation bleeding, a slight rise in BBT will be seen around nine days after ovulation.

Implantation Bleeding or Period Quiz

If you're still unsure about whether you're experiencing implantation bleeding or a regular period, take the interactive quiz now.



The bottom line: Don't forget that once you're pregnant, you will no longer have your normal menstrual period. If you notice that your period is early, very light in quantity, and has changed to a pink or brown color, this may be the first sign of pregnancy. See your doctor for a blood test, which can then accurately confirm the pregnancy.

    I have not been following my calendar. I noticed light blood and little clot today, what could be the problem?

    2. Eam: I have a problem. I didn't have spotting, but after ovulation, I got the feeling like I'm having a fever and period-like cramps. Then after a few days, I felt a pain at the back of my lower hips. Then there was a little pain in my lower abdomen. I took PT and it was negative. - (Sep 21, 2016)

    I'm 3 days post ovulation. I haven't felt "normal" since. We are TTC. My abdomen feels "strange" almost like a stomach ache but not exactly. Somewhat like cramping but mostly just noticable pressure. I had to urinate 2-3 times more than usual yesterday. My period is still 10-12 days away. Are these early signs or am I dreaming?
    1. Sarah (OC Team): Hi Gina, it's hard to know for sure as you can also experience similar symptoms before a period. Have a look at the following article about early signs of pregnancy too. https://www.ovulationcalculator.com/early-signs-pregnancy/ - (Jul 27, 2016)

    Please, I need your help. I have been trying to get pregnant for some months now. I take folic acid every day, but still I test negative. My ovulation is always good and frequent, period is good but is there something hindering implantation? And how do I know if implantation is happening in my body? I am expecting another period in the next four days. I am so eager to know if am pregnant now. I don't want to have another flow. I want to test positive.
    1. Christina (OC Team): The two week wait between ovulation and when you can take a test are difficult. It's normal to feel a little anxious to test. You can only confirm that implantation has occurred with a pregnancy test, but while you wait, you can look for these signs: ovulationcalculator.com/knowledge/ - (Aug 10, 2016)

I discovered I started ovulating 3 days later, and have been having constipation since then. Now, I have my period again without any cramps whatsoever. This started on the 12th of August which is exactly 19 days after my last period. Please, this is the first time am experiencing this. I really want to know what has happened to me. Thank you.

    Hi, my ovulation was on the 20th of August and I had sex throughout my fertile window except on my ovulation day. Today is the 23rd of August, and I had heavy cramping in my left abdomen with brownish blood droplets. The cramping is still there. Please, what could be happening?
    1. Christina (OC Team): Did you take the quiz in this article? Cramping with implantation is usually light, but the spotting could be a sign. It could also be a sign that your period is coming. If you are close to your period date, you can test soon. Good luck! - (Aug 23, 2016)

    I just found out on friday that I'm almost 7 weeks pregnant. I went to the ER because I went to the bathroom and when I wiped, there was blood. It was just a little, though. And there was just a little in the toilet. All they did at the emergency room was take a urine sample an gave me a pregnancy test, which I already knew I was pregnant, then they sent me home. That night and the next day when I went to the bathroom I noticed a very light pink color when I wiped but nothing in the toilet. Should I be worried about a miscarriage? Please note I only have one tube. My last pregnancy I went to get my tubes tied an they forgot one. So I just kept my one tube.

    After my periods (august 6-13), I had sex a week later (august 17). And in 3 days (august 20), I was spotting for 2 hours and stopped. Two days later, I had cramping like if my period was coming, for maybe 4 days. I still have the cramps but not as intense as before. I'm just waiting for my period that I'm expecting by the 6-10 of September. I'm praying for it not to come. Am I preggo?

    I was supposed to have my period on the 8th of August, but I noticed blood immediately. I finished having unprotected sex on the 5th of August, and this bleeding lasted for 3days. Now it's September and I have I not really seen anything up till this day. Initially, pimples and tender breast occurred as always before my period. Until now, the period hasn't shown at all.

    Hello all who are TTC. My last period was August 14th. It lasted 5 days. My ovulation date was 8/27. We had sex on 8/28. Today, I'm experiencing harsh cramping. I'm expecting my period 9/11/16 or 9/14/16. I took a Prego test on Wednesday, but it was negative. Should I test again if my period doesn't show up 9/11?

    Thank you. This was our first try to "see" if anything happens.
    1. Christina (OC Team): If you actually ovulated on the 27th, the 28th would technically be outside of your fertile window. But I would still suggest testing again if your period doesn't show. Good luck! - (Sep 11, 2016)

    1. Christina (OC Team): You must be within your fertile window to get pregnant, and it is highly unlikely that you would get pregnant on the first day of your cycle. However, if you had sex in the previous cycle and only had a two-day period, I'd suggest testing. - (Sep 11, 2016)

My doctor says am perfectly ok, but last month I had sex on my ovulation times and now my period is here early and brownish. I never had any signs that my period was coming. It's meant to come out on the 11th of August. It lasted for three days. What should I do? Please help me. I've been trying for so long and I have no pregnancy signs. I urinate frequently and am having back pain. Thanks.

    Good evening all. I love this site. Please, I have a problem. I have my period on the 11th of every month. Last month, I had it, but on the 19th, I had sex with my bf and we stopped when he was about to release. Now on the 11th & 12th of this month, I haven't seen my period. Please, what is my faith?
    1. Christina (OC Team): Hi Joy, So glad you found some helpful information here. Have you been tracking your cycles? You may have your period around the 11th every month, but it is unlikely that it always falls on the exact same date. If you have a regular cycle, it may be something like 28 days every month. With a 28-day cycle, you could have your period on the 30th of one month and the 27th of another. I suggest you wait a few days to see if your period arrives.

    My husband and i have been ttc and we felt this month was the month. Yesterday, I had light bleeding. Not even enough to put a pad on, though. Then last night, I had a horrible migraine. Woke up this morning and on my way to work, I had to pull the car over to throw up. However, I dont feel sick at all. I'm at work and fine. I was supposed to start my period today, but it hasnt happened yet. I took a test yesterday morning and it said negative. How long should I wait before I take another test?
    1. Christina (OC Team): We usually recommend testing two weeks after ovulation. If it has already been that long, I'd just wait a few days between tests to allow hcg levels to build. Good luck! - (Sep 16, 2016)

    i removed my implant (2 1/2yrs on Aug, 2016) due to bleeding as advised by the doctor. I had a heavy flow for 2 days and later stains. Then I had sex with and without a condom. Can i get pregnant immediately? I am yet to experience my menstrual period because I didn't have regular periods with the implantation.
    1. Christina (OC Team): This depends on whether you are ovulating yet. Unfortunately, there's no way to tell unless you've been tracking. You can try testing two weeks after you had sex, if you think you may have been ovulating. - (Sep 19, 2016)

    I ovulated on the 10th or 11th. I had some spotting during ovulation. I'm not due for my period for 5 more days, and they are usually pretty regular. Today while going to the restroom, I noticed blood. No cramping or any aches like my "normal" period, and now the bleeding has stopped. The blood was bright red. Am I getting too hopeful that this was implantation bleeding and not AF?

    TTC for months now. My monthly cycle is 28 days, but last month it came 2days early (26 cycle) was pinkish in color. The quantity was more than the one in the picture here, but it was odorless/didn't smell. I did home PT, which came out negative. I've been having serious back pain and sharp pains in my stomach. What could it be? And if I'm not pregnant now, what step/drug can I take? I need a reliable gynecologist number too, but I hope it's positive this time.

    I read the article, but still I cling to CM. I'm presently 5dpo and I can't say I'm always wet. Just on and off, but we're TTC. Sometimes I feel excess CM and sometimes dry. What possibly it could be? Shall I consider it as positive sign?
    1. Christina (OC Team): You should expect CM during ovulation and it typically dries up (returns to non-fertile state) after. Some women report having CM after implantation, and others report having the same without implantation. Unfortunately, only a test can tell you whether you're pregnant. Good luck! - (Sep 26, 2016)

    Thanks everyone. My LMP was the 28th of August to the 1st of September. I have a 22 day cycle. My period is supposed to show on the 22nd of September, but it was delayed till the 27th of September. Meanwhile, I had unprotected sex throughout my fertile window and have been experiencing cramps, nausea, fatigue, etc. immediately after my ovulation. I really want to be prego. Please, what's wrong with me? Can somebody help?
    1. Christina (OC Team): Did you get your period today? If not, I'd suggest testing if you haven't already. If you tested early and got a negative result, you can test again. On the other hand, if you did get your period, it could just be an off cycle for you. Good luck! - (Sep 27, 2016)
