We had an ultrasound today, and everything looked great!! The baby's heart rate was 176, and he/she is measuring at 8 weeks 3 days gestation (we're 8w5d) so it's pretty darn close. There also no SCH to be found. She said that it was possible that I may have bled it out. So, for now at least, everything is fine!
I still have to take it easy, but she said there's no reason why I can't go on my vacation in 3 weeks. Yaaaaay!
