Good memory Rae, I was just about to comment.
When I had my hsg the results showed polyps or fibriods, with an hsg they aren't able to determine which. (You could figure out which with an ultrasound.) Mine turned out to be polyps, which grow on the uterine wall. Fibroids can grow from the outside, into the uterus, which make them harder to remove. So I had a hysteroscopy/D&C to investigate and remove them. It was a super easy surgery, I was in and out in I think an hour, maybe 2. You get put under, but you're fine a few hours later. I was just tired later that night, and a bit crampy that night and the next day, but after that was fine. I really think that was a huge factor in why I hadn't gotten pregnant. Depending on where the polyps/fibroids are, it can affect implantation, so the egg might get fertilized, but then can't implant. I had my surgery in December, and got pregnant my second cycle after that.
I'm not sure about any of the other stuff, sorry.

Did my other info make sense?? Let me know if you want any more info.
Rae - Wishing you soooo much luck. Glad the trigger was left out on purpose, and you have a packet of info from your class. I'd be reading it over and over! Were there a few other girls in the class? Oh, and I giggled at the mental picture of your hubby prying open the sharps container!

Good job Mr. Rae!
