The day I got off my period I barely had sex with my boyfriend (Saturday the 8th), but we stuck it in only once barely. Afraid of the pre getting me pregnant, I took the plan B pill Sunday morning the 9th. That was my 3rd time taking the plan B pill. Today is the 14th, 6 days after I barely had intercourse, I am starting to bleed. I am afraid that it is implantation bleeding but it could also be the plan B side effects. We barely stuck it in once and I took the plan B pill! Why is this happening? Please help.

Where do you think sticking it in once a little bit makes any difference from having at it for a half hour?

And THREE times with plan B? Ever hear of birth control? Plan B isn't an excuse to avoid reasonable birth control measures.

Sticking it in a little... barely having intercourse... barely having sex.

I think you need to learn a LOT about human reproduction before you continue having sex...

You either had sex or you didn't... there is no "little bit" you also never get a "little bit pregnant"

Sorry to sound so harsh... but reading from your post... indicates you really don't have the maturity or the knowledge to be having sex yet.

First... ANY sexual contact... no matter how brief can result in a pregnancy... no for of birth control is 100% effective... Plan B is never 100% effective either.

You must understand those points and behave accordingly. And accept the risks of your actions. Which in this case can be an STD or a baby.
