My last shot was on January the 4 2014 of this year and I suppose to take the next shot on April the 4, but I didnt . It been four months now and its August. But me and myboyfriend had sex last week three times and he cum in me. But my period been on for a whole month but in between the day it will come on and then off and sumtime I will spot lightly and then it will be heavy another day. But the other day Friday I went to my doctor appointment and took the Depo Shot. Is it anyway I could be pregnant because my belly button is stretching n it feels weird... Help me please!!! Thnks
