unprotected* in the first sentence.
You would not feel pregnancy symptoms immediately after the protected sex. As specialmom pointed out, it's unlikely if you didn't have lapses between your shots and you were within the window. If you're wanting to avoid pregnancy and want to avoid these sorts of scares, always be sure to use a second form of protection.
Hi there. I'm guessing not if your birth control shots are up to date. No lapse in the shots? Were you in a 'protected' window when you had sex? If so, I would guess you are protected. good luck hon
