My GP sent me for a vaginal ultrasound 3months ago and they found some thickening of my womb, I had a blood test while waiting for a referral to the hospital, blood test showed I had become anemic and my white blood cells are low, I have been bleeding heavily for 4 months now, losing big clots most days, 

2 weeks ago I went to my hospital appointment and had a hysteroscopy and a biopsy, I have recieved a letter with the hysteroscopy findings, no fibroids or polyps, womb thickening is 37.8mm, 

i am now just waiting for the Biopsy results, I am so scared as I just don't know what to expect, the waiting is horrible.

What else can it be if it isn't fibroids or polyps?
