I am 46 yrs old and started with heavy periods 3 yrs ago, after being very regular my entire life. I was put on birth control pills and told I was perimenipausal. I was off them this past year and periods became heavy again with clots, and this past month I have had a period for over a month straight with pelvic pain at times and back aches. I have also started back on the pill. I was also told my uterus is enlarged. Should I be worried, or just continue with the pill and see if my cycle becomes regular? Just wanting some advice.
