I've got a 50/50 track record.
With my first, I was sure she would be a girl, and she was. With my second, I was SURE, SURE it was a girl. At my 20 week u/s I kept asking, are you absolutely sure it's a boy, like 100% sure? They were. I had two more u/s, one due to partial placenta previa and one due to a car accident at 38 weeks, both times I kept asking, still a boy? Yep, still a boy. My pregnancy this time is totally different. It's been MUCH harder, I've been way more sick, more tired, it's been rough. But after two very easy, eerily similar pregnancies that yeilded a boy and a girl, and I have no guess at all! I don't think we are going to find out either, and really, I'm clueless!
