I have been on the depo now for about a year and within the past 2-3 months I have been experiencing some really weird symptoms that I havent had before. I have swallon breasts, my nipples are huge they doubled in size in the past couple weeks which has never happened to me before, I have a small bump on my stomach that even my bf thinks looks like I am pregnant, I have been getting sick, I have extremely painfull back pains which could be the cause of something else, and I have been having extreme headaches when I have only had maybe 10 in my life time and these have been like constant which is also kind of weird. I know there is a slim chance and that on the depo you do experience some pregnancy symptoms, as I have noticed in the past year but this is just way different. I have this weird feeling in my stomach which I just can't pin point what it is. Could I be that 3/1000 who is pregnant? My bf and I are very worried, I am due for my depo right now so If I got pregnant would have been right after I got my shot because I remember that he didn't pull out in time that same day I got it.
