need advice now!

Ca
Last week @ my 38 week checkup babies heart bEat was 180, and dr immediately put me on monitoring and an IV to decrease her heart rate. 
This morning I felt a little off. 
I checked her heart rate on my monitor it's high 180's again. 
Called dr the nurse said don't trust home
Dopplers drink water & if she's moving I should be fine. 
Does anyone else ever have  gut instincts? I feel like something may be going on & I should be checked out today... so do I go to ER or show up at DR and demand to be seen?! 
Crazy FTM here
