Hello, so I need some help. I just got my very first dose of depo provera yesterday on the 14th and My period ended Friday the10th. I had sex 12 hours later and the condom broke and he doesn't know how long the condom was broke. Is there a possible way that I could be pregnant given the fact that I got the shot 4 days after my period and I had sex 12 hours after getting the shot. PLEASE HELP! Thank you.
