I am pretty sure we are going to try and find out this time (we waited until birth to find out with our first, and would have waited with this one, but finding out it's twins has swayed us the other direction) and so I am excited to know. I will be going for an ultrasound in just over two weeks....Thursday the 28th. There's still a chance that we'll decide to be surprised (I'm feeling more together with that option the more I get "used" to the idea of identical twins), but last I checked my husband still felt pretty strongly about finding out.
Assuming babies cooperate. It's an exciting change -- the option of knowing -- and every time I see the announcement threads I get a little thrill at the prospect.
I wish I knew what my intuition is telling me. Every dream and feeling has suggested boys, not that I've had too many of those dreams--but the ones I've had have involved boys. (I honestly can't say if it's a true gut feeling or just a wish/hope. If that makes sense.) I definitely feel most settled about the boy name options (which is how it was with my first pregnancy, when based on timing of conception I told myself it would be a boy but the girl names were most compelling. And she surprised us by being a girl!)
So, my hopes & dreams involve boys for these twins. But somehow the fast (mid-160s) heartbeat rates and the fact that I sort of would prefer two boys to two girls makes me think/fear that it really is going to be two girls. I also thought we had sex very early in my cycle, and that I ovulated early but not THAT early, so the chances of GIRL conception seemed good. (But I honestly don't know the dates and can't vouch for how accurately I'm remembering--no chart or anything.) Anyway, my head is saying, "It's going to be girls."
Which has become kind of a darling thought for me, just in the last couple of days. "You know, actually, two girls wouldn't be so bad...."

All that to say....I'm with you, in suspense!
