Welcome Indi1, I reckon go get the BT done for the interrim between now and the U/S. Will help to put your mind at rest and give you a more enjoyable time over Christmas! As Tash said, your levels were rising well early on, I have no idea what mine have been cos docs have never done them, they always told me it wasn't necessary :P go figure!

Wow Tash that's really early! Are you peeing heaps? That's something I had for most of the first trimester, it drove me incredibly insane as I didn't remember that happening with the other two. Died down after around 10 weeks or so but has started up again of course!

Take care all, I'm heading off on holidays tomorrow so will be away til Christmas! Stay safe and happy and keep all those beautiful babies growing!
