I just got off the depo shot and have only had 3 periods since then. I've been having unprotected sex since then and now for the past few days I've been having cramps that come and go but feel like a cramp before I start, but today I noticed brown spotting then later I was bleeding. When I wake up in the morning I feel like I may get sick but I don't. I have no other symptoms of pregnancy but could I be? I'm not sure what's wrong?

It's possible that you could be pregnant. Are you due for a period at this time? It could be from that as well. If you are due for a period, see what happens over the next few days. If you don't have a usual period, try a test.

It can take quite a long time for periods to become regular and for pregnancy to occur after stopping depo, but some women do find it happens faster than others.

I usually start between the 9th-11th but now it started the 6th. My cramps are very painfull and I'm not bleeding a lot like usual but when I look its both pink and red?
