Oh sweetie, I'm so sorry you're in so much pain. As for the surgery, I don't know anyone who had it. So I can't offer any advice in that department but I'm sure some of the fine ladies we have on YT have experience with that. I just wanted to offer you some support during your tough time. Everything will be fine in the end, it's just a hard road to get there sometimes.
PS - I know this isn't something you're able to consider right now with everything ahead of you but I just wanted to throw this out there and maybe keep it in the back of your mind.
As for wanting a girl and not being able to have one after this operation, I just wanted to share something my husband and I are seriously considering for the future. We want to have one biological child and we want to adopt a child. We did some research and we decided on an international adoption, rather than a domestic adoption. We also did extensive research and we found a very reputable agency called Children's Hope International.

They place children from many China, Columbia, Ethopia, Kazakhstan, Russia and Vietnam. They use to work with Indian but right now there's some problems with the policies, so that's on hold. There are many other wonderful adoption agencies out there but this one just tugged at our hearts.
Please don't feel like this is the end for you in regards to having a daughter. You never know, there just may be a little girl out there who was meant to be your daughter.
Again, I just want to wish you ALL THE BEST with your surgery and if you need someone to talk to or vent, PLEASE feel free to PM me. You will be in my prayers.
