Whew! Everything is ok!
I finally got a call back from the nurse and she said that based on the consistent movement for weeks turning into almost none over the past three days, I needed to go to the hospital asap. So, I went. She kicked me on the way there, so I knew she was alive, but that was only the second movement I'd felt all day, and typically I feel her 6-7 times an hour.
They didn't give me an u/s, but they hooked me up to fhr monitor and a movement monitor. She has a h/b of 150ish, which, of course is good, and she moved a whole lot while I was hooked up, but I could hardly feel any of it. They told me that she had most likely switched positions.
I felt kinda silly going in since everything was ok, but she assured me that it was good that I came in. I feel so relieved, and so blessed that my Norah is ok. Thanks for the good luck vibes ladies!

Re: Update on my decreased fetal movement
You did the right thing by going! I would've freaked out too!!
I'm so glad she's allright
