I've been on the Depo shot for a little under 2 months and I haven't had my period since I've started it. I had unprotected sex a week ago and I took the Plan B pill afterwards because I was nervous. Since I had sex I have been experiencing slight cramps and have had dark brown (and now slightly bloody) discharge. I think I am now on my period but I am nervous because of the weird symptoms I've been having and because of how long it took for my period to come. My period has always been pretty irregular (it used to come about a week later than it was expected the would randomly come early), I have been stressing a lot about not getting my period, and also I wrestle so I regularly have intensive work outs and I have to watch what I eat a lot (and often skip meals). Could I be pregnant or am I just being really paranoid?
