Hi guys i got my first Depo shot on April 9 and i had unprotected sex a couple of days after that and since i was worried the shot hadn't worked i took a plan b pill...now fast forward to a week and a half later i had unprotected sex again with my bf and i was worried so i took plan b again. Now on April 28th my period was supposed to come but it hasn't and i know that that ids normal while on the Depo shot but i have crampig but i am wondering if maybe my depo shot didnt work because of the planb pleeaassee help!! thank you!
