As I said, I had the same but I had a cystoscopy and she had a look and also took cells to check. I think I may have had an ultrasound at some point before that because I had been in hospital a few months before. I think these are just tests that they do to eliminate things and be sure everything is ok. You wont be able to stop worrying, I think we all worry about the same things when we need tests, but hopefully everything will be fine
