About a week ago I let my boyfriend ejaculate in me for the first time in our 2 year relationship. The first six months or so of our relationship I wasn't on the pill and we never used a condom and I never got prenant then, i've been on the pill now for almost a year and have never missed a pill (atleast I don't think I have, one night I coughed while tryin to swallow my pill with liquid and i'm pretty sure the pill went down but am not entirely sure) anyway, the incident with the pill swallowing was almost 2 months ago, what are my chances of being pregnant? Please someone say I wont be because i'm only 20 and in college and I want to finish my schooling before I have children, please help!
