I have been bleeding for over two months now and I did have a depo shot for the first time about 3 1/2 months ago but never went back for a second because my and my fiance decided to try for a baby and now we can't tell if I may be pregnant or not and i did not get a test yet. I just want to know is the bleeding a combination of being pregnant and the one depo shot I got or what. Any thoughts or similar situations ?
