Hi Emmy, I'm no expert, but I'm guessing that the swabs/internal were to check for any infection (like a smear?), so if that came back all clear, that's a good thing!
I'm also in that same position as you, with having all-clear blood tests and a 'good' SA result for hubby. We're currently on the waiting list for IUI, and IVF if we need to go down that route. I have been told by my consultant that I don't require any medication at this stage, as there is noting to "fix", if you know what I mean? We will probably have medication for the IUI and IVF, just to make sure that everything is happening at the right time.
Hope that answers your questions, although I'm sure your GP would be more than happy to talk to you if you're still anxious. I did, and they are used to having people coming back - it's a lot to take in!
Good luck xx
