I am 52 years old had a period in November, 2007 then no period until May, 2008. No problems in May and June, but this month having a very heavy period. Doctor is did a endometrial biopsy, is this normal for this problem? I am hoping that the reason for the biopsy is to see if I am moving toward menapause and not cancer. Just want some reassurnce that this is something that happens to may women and I will be ok.
