I had my last shot around 8-10 weeks ago. I'm scheduled to have my next shot for December 6-16, but I just started my period over the weekend. Once my period ends, is it safe for me to have sex without a condom or do I need to wait for my next shot to have sex again? I'm just wondering if having a period means the shot has worn off and I need to wait to have sex until my next shot to prevent pregnancy. This is my first time using it while having sex as I just got married a month ago.
