Hi I'm a 25 year old female. It will be a year next month since I haven't taken my depo shot, and I haven't had a period since then. Well my boyfriend was visiting me for a week and we had been having sex pretty much the entire week he was here. The last official day we had sex was Last Friday August 22 and I've been like spotting ever since then..we'll actually like the 2nd day after having sex with him. And not to mention I was sore and STILL having sex..I don't have sex often because I'm in a long distant relationship. So I'm wondering if it's because my period is coming back from being off the depo shot or we just had too much sex
