Remember how you used contraception with the thought that pregnancy was looming around every corner?! 😀 It turns out it’s not that simple! Every month, an egg is released. Once released, an egg only actually survives for between 12 to 24 hours if it is not fertilised. There’s only a small window each month during which you can conceive, usually about six days. The time leading up to ovulation is when you are most fertile. This is known as the Fertile Window.
On the other side of the fertility tango, sperm can live inside your body for up to seven days. You would want to have sex during the fertile window so that sperm is ready and in position to meet the egg when it is released.
OPKs are one way to pinpoint ovulation. The test strip measures your LH surge. LH is Luteinising Hormone, and its levels surge one to two days before ovulation. If I can see when the LH in my body surges, I know that ovulation is going to happen in the next day or two, and so it could be useful to have the sperm in my body, ready and waiting for the egg to be released. So, I recently bought cheap Ovulation Predictor Kit (OPK) test strips.
They claim to predict ovulation with 99.9% accuracy. I’ll take those odds! Ideally, you don’t drink or eat at least 2 hours before you collect your urine. The best time of day to do the collection is between 10am and 2pm. Once collected, you put the test strip into the urine for 10 seconds, remove, and then wait for the results to show. The control line is on the right, the test line is on the left. If the test line is the same or darker than the control line, the result is positive and ovulation will likely happen in the next 24 – 48 hours. These are my results, one test a day for five days:
As you can see, my body was gearing up for ovulation with the LH surge on day 3 of testing. On day 4 of testing, I was likely coming down from the LH surge and by day 5, the LH surge was over. Using these test results, I would say that I ovulated during the evening of day 3 🙂
I am using these OPKs in conjuction with the SMEP Method of conception and so far I feel confident. I do believe that the OPK strips worked in identifying when I was going to ovulate. I do believe that the cheapies that I bought are worthwhile and accurate. So fingers crossed for fertilization and conception this month! We should know in about two weeks if anything stuck this cycle!
