Trying to Conceive: Your Ovulation Calendar. Many couples rely on ovulation predictor kits, or OPKs, to identify when the woman is most fertile. OPKs can detect a surge in the production of luteinizing hormone (LH), which occurs roughly 36 hours before ovulation. By timing intercourse shortly after the LH surge, you can increase your odds of bringing sperm and egg together at the time when conception is most likely to occur.
This is where ovulation predictor kits (OPKs) can help. An OPK is a quick, easy and accurate way to predict ovulation in advance. It allows you to pinpoint your fertile window from the very first month. Kits are available online, at some chemists or medical stores that also stock pregnancy test kits. Urine-based OPKs test your urine for an increase (surge) in luteinising hormone (LH). This happens one day to two days before ovulation. A small amount of LH is always present in your blood and urine.
