Last year during my yearly exam i had a pelvic ultrasound/vaginal ultrasound and they said my endometrium lining was thick,they did a biopsy and said everything looked ok with that,and really never said anything else.Well i went back this year for my yearly exam and they did another pelvic ultrasound/vaginal ultrasound and said again that my endometrium lining is thick.The nurse talked like they may do another biopsy,but why would they do another one if the first one was fine? wich was done only a year ago, if the biopsy didnt show any endometrial cancer last year what else is there that it could possibly be? I am 31 years old i have 4 kids,no miscarragess no abortions no birth control,my periods are every 27 to 31 days sometimes i will bleed heavy and then sometimes only for 2 or 3 days. Thank You
