Glad you're keeping us posted; I've been thinking about you all weekend! Word of caution about that doppler: It is often very hard even for medical professionals to find heartbeats on our hospital-grade dopplers, even at > 12 weeks, even when the baby is perfectly healthy, so PLEASE don't fret too much if you can't find it!
L (40), wife to C (40), mom to dd C (19) freshman in college and world traveller, and ds K (16) ballet dancer and high school junior, and expecting #3 April 1st 2015. I'm a homeschool veteran (12 yrs) and full-time RN, my first two were natural hospital births and I breastfed both of them. Also, I won't tell you how much my kids weighed at birth, and I'll never ask anyone else, because I think it's TMI to know how much poundage someone passed through their wawaha.
