Patient: So I take Yasmin and I missed three days in a row, and was on antibiotics, is it possible that I could be pregnant. I have missed my period, I am a whole week late.
Doctor: Missing three days of oral contraceptive will definitely increase the chances of pregnancy. The use of antibiotics thoug h may not decrease the effectiveness of Yasmin. Since you’ve missed your periods and are a week late, I would suggest that you do a pregnancy test to find out whether you are pregnant or not.
