I m 24 years with one child and I am on and have have two rounds of the depo and my next shot is on the 13th. My boyfriend and I have nt been using protection and the last week I have been having a few pregnancy symptoms. Nausea, cravings, fatigue, mood swings, and tinder breasts. I ve taken an at home pregnancy test and it came up negative. Should I ask my OBGYN for a blood test when I go in for my next shot to be sure or is this normal for the depo.
