I had the depo shot only once and the 2nd one was due on feb 4th. I didnt go get the shot. About a week ago march 12th me and my bf had unprotected sex. I had been bleeding non stop since I had got the shot. I had all classic signs of getting my menstra; period. That night was when we had sex march 12th. The next day half way through the day I stopped bleeding. And a week later still no bleeding but I keep getting cramps through out the day and recently bout 3 days ago in the mornings and sometimes at night after I eat I feel sick to my stomach. My sex drive is alot more than before. Im alot more tired and more hungry. Could I be pregnant? I have two other kids and with both kids i never had morning sickness. My youngest is 10 months and my oldest will b 3 soon.
