I had my son on December 29 and I got my depo shot on Feb. 20. I had my period March 26 or 27 it lasted for like 2 weeks, and about a week and a half later it came back and lasted about a week. Ok today is May 26 and I haven't had a period yet. Is this because of the depo or could I be preggers? Of course I've had sex with out a condom since I've gotten my shot. Just curious cause I'm not ready for another little one just yet. Someone help please and thank you!
