Hi Becky,
sorry to hear you have Ashermans, it is a very scary thing to go through. Have you signed up on the yahoo group yet? If you havent yet, please do so ASAP. The information on there is very very valuable and there is fantastic support too.
health.groups.yahoo.com/group/Ashermans/
(There is a UK sub group too, but you will find more documents on the main group)
The best thing they do is keep lists of doctors who have successfully treated AS, which include NHS doctors too. Dr Anthony Trew who works out of Hammersmith is on the "A list" and there are a couple of others on the "C list" IT IS REALLY IMPORTANT THAT THE PERSON DOING YOUR SURGERY HAS LOTS OF EXPERIENCE WITH ASHERMANS CASES. As many women on the yahoo board will tell you, if your first surgery is not done correctly there is much more chance of your scarring getting worse not better. Lots of British women have pushed to get treated by Dr Trew and went on to have babies afterwards. You are entitled to ask for a referral to someone with experience in this area, you do not have to accept having your surgery done by any old gynecologist.
You need to find a doctor that has done at least one AS surgery a month during the last year, and who can show that the women they treated went on to have successful pregnancies afterwards. They must only use micro scissors for cutting, no lasers, and you need a 6 week course of estrogen (6mg) afterwards - NOT the pill as this thins the lining. A coil can be useful depending on where the scar tissue is, sometimes a stent balloon or spray gel is used instead. You also need to make sure they give you antibiotics via IV during the op or a five day course of antibiotics starting the day before surgery. If it doesnt sound like you will get this kind of care, then dont do the surgery!
There is a really good document called "Questions for your doctor" (on the yahoo group, files section) that can help you work through all the areas so that you can be sure your doctor is going to treat you in the right way. PLEASE DONT LET SOMEONE UNQUALIFIED DO YOUR SURGERY. That would really put your future fertility at risk.
I hope it gives you hope to know that I didnt have any periods at all either, and even though this classifies you as "severe" if the scar tissue is limited to your cervix area and preventing blood from escaping, this is one of the easiest places to remove scar tissue from. Provided that the surgeon knows what they are doing, you have a very good chance of getting this fixed and getting your fertility back.
Its really really worth making sure your first surgery is done right, that way it will be your ONLY surgery.
best wishes,
