Shell, my mother suffered with this for years, and she had such major haemorrages every month, i remember my dad telling me when i was 11-12 to go to the public loo with her when we were shopping, just to make sure she didnt pass out. She even had to take hand towels with her, and i remember them being soaked.
When i was 12, she had to have a total hysterectomy, as the doctor was afraid she would bleed to death with one of these haemorrages. She was fine after that, but she too suffered in silence for so many years.
I am so happy that you are pregnant, and I really hope that with all the modern treatments available now, that you do not have to suffer anymore from this terrible disease.
Wishing you a very Healthy and happy pregnancy
