I took the depo shot august 3 2017. I had breakthrough bleeding throughout the duration of the shot so I didn't get my second shot which was due Oct 26. Went to see my doctor Nov 7 and he gave me dicynone and norculut to stop the bleeding and antibiotics for infection in my urine. The bleeding stopped and I had unprotected sex Nov 19. Had my period Nov 21 and it lasted 8 days. Had unprotected sex again Dec 8, 12 and 13. My period hasn't come since and I'm having pregnancy symptoms. Did a test which was negative and after the test I had pinkish spotting for about 3 days. My breasts feels weird I'm nauseous and easily tired. I get cramps which feels like menstrual cramps but nothing. Please help. 

Thank you.
