Is it possible to get pregnant 2 weeks after my period if i take birth control?

Always a chance.....: Birth control pills are a good method of birth control, but if you missed a dose, were very late with a dose, took certain antibiotics, etc., it can make the pill less effective, so, if your period is late, check a test. Also, at 15 you should be using a condom in addition to being on the pill. Remember that the pill won't protect you from herpes, hiv, etc. He'll say he's "clean" even if not.
