I missed two days of bc pills, we had sex every day but used the pull out method. i was on amoxicillin the week before. light spotting now. pregnant?

Maybe no but do test: It can be hard to tell if a woman is pregnant because some of the symptoms seen in early pregnancy can also happen in non-pregnant women. A urine pregnancy test gives a reliable result if done correctly. One can test about 3 weeks after sex (when conception might have occurred). An ob-gyn doctor can evaluate any persistent or worrisome symptoms.
