Hi, i recently had unprotected sex with my boyfriend.. he used the pull out method. my period arrived a day or two later. usually it's heavy and painful but it's kind of light with mild pain. could there be a possibility of my being pregnant?

Well,..: The pull out method is one of the least effective forms of birth control, so there is always the chance of being pregnant. Assuming you indeed had a period, it is unlikely that you're pregnant, but if you want to be safe,..check a pregnancy test. In the future, do not rely on the man to "pull out, as 'pre-cum' may have some sperm in it as well. Use BC and condoms to prevent preg and STI's.
