I was on the dep shot for 3 years well i couldnt afford it any more and had to quit taking it its been 3 months since i quit taking it. I know they say it may take up to a year for you to get pregnant, but the last month or so my breast have swollen and their constantly sore. Ive had a little brown discharge for a few days and am nauseated sometimes plus ive been wanting to eat food i dont even like... Am i pregnant do i need to go see a doctor?
