I have been on the depo provera shot for almost a year now, however at the end of june i got my period, which i've never had before while on the shot. I had a little boy just over a year and a half ago. since the middle of september i have noticed that my breasts have gotten bigger, i've gained weight strictly in my stomache, i've been increasingly fatigued and certain things are really affecting my gag reflex or nauseating me. i also think that i have felt the "quickening" if i was as far along as i should be according to my period it would be 16 weeks. I saw a dr last week and she sent me for a urine test and it was negative. any thoughts??
