Please don't feel bad for feeling this way. I don't understand why gender disappointment is so taboo in our culture. It's a very real and very common thing.
I will tell you this. At a 12 week ultrasound of the twins, the specialist said he was "pretty sure" he could tell us the genders. He said he was 100% sure baby A was a boy and fairly certain that baby B was too.
I sobbed all the way home. I'm not talking about a little crying, a few sad feelings, or whatever. I was bawling my eyes out.
It made absolutely no sense for me to be that upset. We had gone through hell to conceive and stay pregnant with those babies. That was the first time in almost three years I'd made it to 12 weeks and seen a heartbeat (much less two heartbeats). I should have been elated no matter if they were boys, girls, or giraffes.
The next week was really hard for me. I didn't want to tell anybody about the genders (we hadn't told many people about the pregnancy yet, so that worked out). I felt incredibly guilty for being even the slightest bit disappointed about two healthy babies. I didn't know how to process my feelings at all.
In our case, by the next ultrasound they were 99% sure Baby A was a boy, and 90% sure Baby B was a girl, which turned out to be accurate. So I don't have advice for how to deal with the disappointment (although I know you will, just as I would have). But I just wanted to let you know that you're not alone in how you feel, and you're not horrible for feeling that way.
Oh, and as much as I wanted a daughter, DD has been quite a handful from Day 1, while DS2 is an absolute angel baby, and VERY attached to his mama.

The biggest mistake I made is the one that most of us make...I did not live in the moment enough. I wish I had not been in such a hurry to get on to the next thing: dinner, bath, book bed. I wish I had treasured the doing a little more and the getting it done a little less. - Anna Quindlen
