I have been having heavy bleeding for the past few years and this last year my periods don't stop all month sometimes. My HGB has gone quite low sometimes. I have been on Bio-identical hormone replacement since last summer which has helped slow the bleeding but it has come back now. My ultrasound from 1-1/2 years ago says I had possibly at least one, maybe more fibroids, 1.5 x 1.3 x 1.4 cm. I have been getting some small cramping around my lower abdomen and I get very gassy and constipated allot and have been not eating gluten as this makes it much worse. I am also hypo-thyroid which complicates things. My doctor has suggested an ablation. I have read that this often doesn't work and can cause some pretty severe problems with a thick endometrium. How concerned should I be?
