I went and got my depo in April of this year and the doctor made me another appt in may but I thought maybe she mistaked cause it last for three months! Well I'm trying to figure out what's rong with me I don't eat right I feel sick sometimes everyday I took a pregnancy test but it was negative.. I sleep a lot I'm always yawning and I cramp in my stomach like period cramps but no period what does it sound like to u?

You should have gone back in May like she scheduled you. Guessing about what's wrong online would be just guessing, with little to go on. Take another pregnancy test and meanwhile, call and make another appt.
