The trying-to-conceive journey is not always easy, as the chances for a healthy woman to get pregnant per cycle is only 25%.


Luckily, there are various of methods to pinpoint the best time frame to conceive during a cycle. Ovulation Predictor Kits is one of the easiest and most effective ways for a woman to predict her most fertile window of the month regardless of the cycle length.


Let’s take a look at how it works:

24-36 hrs before your ovary releases the egg, the LH (luteinizing hormone) in your body will reach its peak, which can be easily picked up by a home ovulation test.


A positive result of a OPK indicates that you are at your LH surge.


Most women get positive OPK tests two days in a row. That’s because LH surge happens 24-36 hours right before ovulation and happens again during ovulation. It’s normal to have positive OPK results within 48 hours.


Which is the Best Ovulation Predictor Kits (OPK)?

There are various OPK brands over the market that sometimes it’s very difficult to figure out which one is the best fit. Before you hit the buy box, take a look at the following good rating OPK brands that people usually like:
