My girlfriend and I had unprotected sex last Wednesday. I pulled out but we weren’t sure if I had done so successfully. She took Plan B. She was expecting her period in the next 2 days, but never got it. She takes birth control BUT she was on the week where she doesn’t take the pill.. She is now starting on the pill again on Monday and I’m freaking out. She says her period won’t come for another month. Will it come? Is she possibly pregnant with these facts? I know it’s a chance but how high?
