My name is Levi, I'm 21 and in February of this year, I gave birth to my second daughter. I got the depo shot the day of my discharge from the hospital and that was nearly 3 months ago. Me and my fiancé have been having unprotected sex since three weeks after she was born and I'm not sure if I'm pregnant. I'm scared because I just had a baby and I don't know what that would do to my system. I'm bleeding but it's not a normal period, please help !
