So, the hysteroscopy went well. At least, I think it did. No serious complications so far. It's hard to judge the bleeding because the sort that happens every month decided now would be a fine time to go off as well. Hopefully I can stay out of the hospital for a while.
I feel obliged to try another pregnancy after going to all this trouble, but I'd rather not try it right away. Probably after we move next year. Because the last thing I want is to be a helpless invalid when it's time to move house.
They said they would probably have to do a laparoscopy, but might not. They never told me whether they actually did it, and there isn't any information in my print-outs. Oh, well. Not having any pain has to be a good sign.
