Can you get pregnant even if ovulation test negative?

Can I get pregnant if the ovulation test is negative? If the test is performed correctly and the LH surge has not yet occurred, you cannot get pregnant.

When will I ovulate after LH peak?

Ovulation is considered to occur 28-36 hours after the beginning of the LH rise or 8-20 hours after the LH peak. Daily assessment of the preovular rise in estrogen reflects Graafian follicle development but the rise is less distinct and spread over 3-4 days with marked day to day fluctuations.

Can you still get pregnant with a low LH surge?

Why do ovulation tests not work with PCOS?

The most popular type of ovulation test kit uses a urine dipstick to measure luteinizing hormone (LH) or estrogen for the expected peaks around ovulation. But if you have PCOS, you may have a constant high level or multiple peaks of these hormones. The results can falsely reflect whether or not you have ovulated.
