I had unprotected "sex" but the penis never went inside, after that I got on birth Control (implant) its been more then 7 days that I have been on birth control. Days later I had unprotected sex, and yes the penis went inside. Now yesturday I thought my period had come, because blood came out. So what I did is that I used a tampon and a pad, hours later I went to check if I had bled more, and literally there was no blood... So I'm really confused now, and today still no blood. And I've been waiting for my period because I'm not sure if I'm pregnant?? Can someone explain this??
