For the past two weeks Ive been spotting on and off. I am 19 and have been on the depo shot since April. As far as I know I don't have any medical issues. When it first started I had cramps for the first day. Since then its been anywhere from half a day to two days apart and anytime I think I'm good and have sex it starts again immediately. Its been going on for 9 days. Ive taken two pregnancy test 4 and 5 days ago and they were negative.

Should I take more tests? What could be the cause for it not stopping.possibly pregnancy? HELP ME!!

I think it is caused by the depo shot. I'd wait and see if you adjust to it. You could call your doctor and double check. You could try a different birth control if it doesn't get better.

I was on the shot for years and never had any problem. I went off the shot for about 6 months and ended up going back on it. About a month and a half after I got my 1st injection I was spotting for about 3 weeks. I waited it out, got my second shot and now I've stopped menstrating.

Hope that helps. Good luck!

Go to the gynocologist! Its highly unlikely that you would get pregnant on the depo.
