endometriosis
"On Depo for approximately 10 yrs go. No problems or side-effects. No period for 3 yrs-HEAVEN! Got off of it. Doctor said since I had no bleeding last time would be okay to do again. Got shot a month ago-the week I was supposed to start. First week was great. No bleeding but have had continual spotting every day since (3wks). Hopefully it will stop soon. "
