I know I squealed. I already knew about the forum, but for once I could answer questions instead of ask them.

I tested 13 times before we had our first u/s to confirm at 8 weeks. It was nice reassurance. We waited until the end of the first trimester to start spreading the word though since that's when your risk of m/c really drops. My cousin made the announcement they were expecting #2 just after their confirmation u/s only to m/c a couple weeks later so it would have spared them the difficulty of telling everybody what happened.
I hope that your numbers come back nice and high and that you have a wonderful 9 months. Congrats mama! Lots of sticky dust!
