Missed Period & Negative Pregnancy Tests: What Are My Chances?

Question
My last period was September 1. I missed a lot of pills since then
I had unprotected sex on September 22 and was supposed to start on the 29th and I didn't. I have taken three home pregnancy tests and they were all negative. What are my odds of being pregnant?

Answer
As long as your pregnancy test is negative, you're probably not pregnant.  Some women miss periods while taking the pill.  It's like how most women get lighter periods on the pill, and sometimes they get so light they don't come at all.  I would keep taking the pill normally.  If your period doesn't come this month, and your test is still negative, you could ask your doctor to switch pills, and you would probably get your period.  However, it's not harmful to not have periods while taking the pill.
