Will ovulation tests work if you're pregnant? Ovulation tests can (sort of) act as a pregnancy test because LH is molecularly very similar to hCG. If you are pregnant, your hCG levels will be much higher than normal and an OPK may inaccurately detect this and read it as a high LH value.

Predicting ovulation is easier when you have a regular menstrual cycle. With a 28-day cycle, you'll likely ovulate on or around day 14, so you'll want to start testing around day 10 or 11.
