Went to the OB this afternoon. She was running behind, and the 40 min. wait was torture, as I was dying to know if LO was okay!
When we finally got a look at baby on screen, he/she was probably asleep (with one fist propped against their cheek -- so cute!), so there wasn't much movement. I guess the Dr. could tell that that worried me, so she poked a bit to see if we could get LO to react. The response was only a tiny bit of stretching/stirring -- but the hb was a solid 160 bpm, and the placenta was intact, with no signs of trauma.
This + the fact that baby seemed so calm and content, was good enough for me. Thanks for all your encouragement and good wishes! They definitely helped!
