Missed Period - Negative Pregnancy Test

Q: I missed my period but my pregnancy test is negative. What does this mean?

A: Pregnancy tests are usually very reliable, and 98% of the pregnancy tests are positive 15+ days after ovulation. If your test is negative, then you are either not pregnant or the test was done too early. In the absence of pregnancy, you can miss your period if you did not ovulate (anovulation).
