To make it as short&sweet as possible:I have been on depo before when I was 15-16. No period, or PMS related symptoms. I am now 21, and got my first depo injection in May of this year. I was 2 weeks late recieving my second shot. During that two weeks, I had unprotected sex with my long term boyfriend...because Im on the shot and should be fine, right? The nurse that administered the second shot didnt give me a pregnancy test, and I was unaware that she should have. After my late shot/no condom fiasco, I have since spotted both light and heavy at random points since then. Its been 2 months since my last shot, and my cramps are horrible right now. Should I see my dr right away? Or am I safe to wait until my next shot is due to see him?
