Video Transcript

I'm Dr. Tash. This is an ovulation predictor kit. Here's how to use it.

There are two types of ovulation predictor kits. One uses saliva, the other, urine. Today we're going to be focusing on urine.

People often get the timing wrong and then they wonder why they're not getting pregnant. The great thing about the ovulation predictor kit is it tells you when to start having sex, because you want to start having sex before the egg is released. Because really the sperm should be there when the egg is released to maximize the chances of fertilization and pregnancy.

These kits are a great way of you monitoring your fertile window at home. And that's really important, because once you've ovulated, that egg only has 12 to 24 hours to become fertilized. So it's really important you're aware of your fertile window before you ovulate.

The kit works by detecting luteinizing hormone, or LH, levels in your urine. Now, about 24 hours before you ovulate, LH levels surge. They rise quite quickly, and that is an indicator that you're going to ovulate quite soon.

There are many different kits on the market. Just read the instructions. In general, I recommend you don't pee for about four hours before you use the kit and when you detect an LH surge for the first time, that means you need to start going for it. You need to start having sex, because it means the fertile window is open.

People often ask me, "How often should we have sex?" I recommend that as soon as you detect that LH surge, have sex every day, every day in the lead-up to and the day of ovulation. That'll maximize your chances of falling pregnant.

    What if you are trying to have sex three days before your ovulation day to maximize you getting a girl? How will you know the days. I mean the days ahead to ovulation. Since it doesn't tell you the exact day of your ovulation.
    1. Christina (OC Team): You'll have to keep track (you can use your ovulation calculator account) and predict when you will ovulate next cycle. Good luck! - (Oct 29, 2016)

    I run a 29-day cycle. I ovulated on the 15th / 15 days counting from the first day of my menstral circle. When exactly can I have sex with my husband to get a baby boy while taking clomid.
    1. Christina (OC Team): If you log your cycle data into your account here, you'll get a prediction of your fertile window with a suggestion of when to have sex for a boy or girl (based on the Shettles Method). - (Dec 02, 2016)
