I got birth control for the first Time for this month (Trinessa 28's). Me and my boyfriend had unprotected sex during the light blue pills and the white pills. He did it inside me both times. I've had some but not all pregnancy symptoms and I didn't know you had to wait for the birth control pills to get used to your body. But now I think I'm on my period but then I started reading about implantation bleeding? Could I be pregnant?

Of course, you may be, almost none of the birth control pills are effective the first month you start them.

So now you have to wait and see if you have your period when it is due next.
