Since this was 15 or so years ago -- I honestly don't remember (how long the duration was of heavy menstruation). It eventually did "normalize".
Do you notice far less cramping now, though? I did.
I can't report back on how it goes, since I had a hysterectomy since then (stage 4 carcinoma, out of the blue despite *regular* pap tests).
Oddly (or perhaps not so oddly) I had two astrologers tell me "watch out for your reproductive organs" in my teen years. I think it has to do with my Mercury in R in Scorpio in a bad aspect to something else. Very interesting that this was the biggest admonishment (or biggest TWO) I ever got from astrology.
Well, that was a rollercoaster of a response! Hang in there -- you need the stuff cleared out of your liver, that's for sure! (can you use a diaphram sometimes to stem the flow?)
