Well ladies, thanks for your support! Weird feeling it certainly was, some moderate cramping, but nothing awful. And my uterus is so special it made my doctor go "wow"
Good news - both fallopian tubes are open and viable, only 1 tiny (1cm) possible fibroid in the lining
Bad news - I've got a bunny eared uterus, in a big way. Nothing my doc has quite seen before. He's not sure at this point if it means I've got a gigundo septum that's separating the uterus in half or that my uterine tubes never got together in the first place.
Next step is to go visit an RE. So he gave me 2 referrals and we'll see what their input is. It's really nice that I've already had the MRI and HSG - that gives the RE more information to go by. Other good news is that we have the right insurance - apparently all the REs in this town work for the same company so if you have the wrong insurance you're screwed and have to drive 2-3 hours away.
I'm feeling pretty calm about it all. I just look at it as the next step to take to find out more information. I'm actually really grateful to have found all of this out before I got pregnant and perhaps had various problems.
DH keeps telling me not to worry, that we'll be ok even if we can't have kids, but I don't feel anywhere near ready to assume we can't have kids. Just didn't think it would be quite this complicated! Well, on we go!
Thanks again for your help today!
