NST after Falling

I kinda fell down my stairs earlier today. I called my OB and it happened to be a Saturday in which he was actually in the office seeing patients. They did a NST and I was not fully prepared for what was to happen. After strapping me in and telling my husband and I that we need to go get them if the machine stops reading the heartrate. She was very active while the test was going and when she moved the first time her heartrate jumped up and it made me think something was wrong, then it settled down and leveled out until she moved again. The first time it happened my heart jumped out of my chest and I started freaking out. My husband calmed me down though.

End of the test my OB comes back and says we have a very happy active baby. And that everything looks good so far. Going to do an ultrasound on Monday just to double check everything.

I'm 35 weeks
