Gosh - I just thought of something important to add - but by the time I opened up the thread I had forgotten already - will try and think of what it was. It was possibly a question.
Trying the misoprotsol first this time again - they're now combining it with another drug that increases its success rate from 60-80%. Hoping it works.
Edit: I remembered!!! Wonders will never cease. The other thing that doesn't make sense is why we had three successful pregnancies first with no problems and are now having problems. I did have a bleed with our 3rd at 15 weeks and was tender for about a month afterwards, but no signs of problems in the uterus - they put it down to a small placental abruption.
