Your bf pulls out and your 3 days late on ur period and its first brown then pink and light brown and then jus light pink and pregnancy test was negative can you be pregnant?

It's possible. What are you doing having unprotected sex, anyway? Pulling out is not Birth Control, its gambling -- and the odds are waaaay against you!.

Make him wear a condom the whole time he's in. It's your body and your life. He's not the one who will get pregnant.
