I am 10 days post lap chole gallbladder removal. I'm a 34 year old woman. I am on the Depo shot for birth control (the last shot I received was July 9th - my next one is due in October), therefore, I never get a period. However, 5 days post surgery, I got my period and I still have it. Is this normal? I thought maybe it started because I was straining so hard to have a bowel movement. My last pap test was at the end of April and it was normal. Now, I'm worried something may be really wrong. Is this common - my situation?
