i have been off depo for 4 months after being on it for 3 years no periods since starting it and havent had any yet after stopping it. i have been having terrible cramping and back pains. had unprotected sex on the 8th of sept. The pelvic pain ive been having is like menstrual cramping but no period. my stomach is distended and has been for awhile and i had sex with my bf 8 days ago so i know the stomach distention isnt caused by pregnancy and im wondering if this cramping and pain ive had for the majority of last week and this week is from anything serious. been to the er 4 times in two weeks with this pain they tested my urine and blood did a cat scan of my abdomen and pelvic area and an ultrasound to see if i had cystes all were normal ive also had bad indigestion and yesterday i began to vomit. at the er they gave me an iv pain killer (dont remember the name) and the pain went away 2 hours later after drinking the nasty contrast for the ct scan the pain killer began to wear off and the pain was back with a vengeance it was so bad i cried and was in a fetal position in my hospital bed. i am 17 and scared because no one knows whats wrong. any one know whats wrong or have had some of the same symptoms? plz any suggestions?
