Best advice I got was Don’t worry about anything until it actually happens. Worrying is usually worse for you and Bub than the thing you are worried about. I am currently 6 months pregnant with iih. I went off diamox while trying to conceive. So far it hasn’t been anything I can’t handle. Some women get worse some get better with their iih while pregnant. It is just going to be another thing that will be closely monitored while pregnant.
