28 weeks and 2 days!

FINALLY the third trimester!!  I'm starting to feel really huge and those wonderful complaints from the first trimester are back in full swing-moodiness, tired, etc.
I could've sworn that the baby dropped, and one of my residents at work noticed too.  I'm happy that I have an ultrasound tomorrow to check the location of the placenta, (it was low-lying at 18 weeks) and a doctors appointment the following day.  So I will be asking.  I've had some painful (not bad at all, but it did wake me up) braxton hicks, and I want to know if that's normal.  I'm SO paranoid because my waters broke with my son at 35 weeks and a few days.

Anyways, I'm crossing my fingers for good news with the ultrasound and doctors appointment!
