Here's a little background,.......In late November I started depo the shot expired in mid February and I never got a new one. I only got that one injection and prior to this I had pretty regular periods. I had one period while on it and January and it was long asf. Since getting off BC in February I have not experienced a period and I am having unprotected sex (not pulling out either) at least once a week. I took a pregnancy test early March just to check it was BFN so I carried on.

Fast forward to a few days ago.........

I started cramping and assumed my period was starting back up since I've been pretty moody with headaches. Also so nasueated i can barely eat.For 3 days in a row(not counting today)I cramped on and off throughout the day and spotted only first thing in the morning. Is it implantation or?
