Hi,I am on yaz birh control pills and have never missed a pill or taken one late.  However I was on apo-clindamycin (300mg).  I had sex 5 days after being off of the antiobiotics.  He did not ejuculate at all, however I understand that precum may contain sperm but I am pretty sure he urinated prior to having sex.  Should I be worried about being pregnant?Thank You
Hi there, I have understood your concern. I will suggest you the best possible treatment options. As you have mentioned that you were quite regularly taking the birth control pills, you need not worry about the pregnancy. Your concern about consumption of antibiotics is also right. But taking antibiotics for 5 days should not interfere with the action of oral contraceptive pills. So please wait for the expected date of the cycle.  I hope this answer helps you. Thanks Chat Doctor.
