I had.sua with my last baby. the test is just what clysta said. real easy, nothing big. try not to stress about it. you get to see the growth every week it's pretty cool :) good luck!
Maybe that's what it is. I never had any problems during pregnancy with my other kids so this is just stressful 2 me
I've had a non-stress test done during my pregnancy. It's really easy and a bit boring. You go in, they hook you up to this machine and monitor baby movements and their heartbeat after.
