Question
I have been taking birth control for a couple of years now and never have skipped a period. This month I have skipped a period which isnt normal for me. I also have endometriosis and have had un-protective sex while taking antiobiotics. Is there any possible way I could be pregnant?

Answer
It's not too unusual to skip a period on the pill even if it's never happened before.  Antibiotics probably have very little effect on your protection with birth control pills.  So you're probably not pregnant if you've taken the pill every day.  However nothing is perfect.  If you're worried, get a pregnancy test.  Even with perfect use a few women get pregnant on the pill.
