Back in July I had my first depo injection, and on October the 15th this year which was exactally 12 weeks after my first injection I got my second one. On that same day after I got the second depo I slept with my boyfriend and he did cum inside me. I'm a little worried could I be pregnant? Iv been having stomach pains but that's about it. Do you still have to wait 7 days to have sex after every depo injection? PLEASE HELP :(
