Heart rate to fast

A

Went for a routine checkup at my endocrinologist and my heart rate is extremely high the first time she checked it it was reading 105 she than came back a few minutes later and it was reading 112 I'm waiting for her to check it again in the mean time my mother called my obgyn she told me to go to the hospital so I will be going as soon as I leave here. I'm trying not to freak out so it doesn't go any higher but has anyone experinaced this if so what did you have to do

Update: got to the hospital the doctor said its normal to have a elevated heart rate when pregnant but they did a ekg just in case it came back abnormal so now I'll be doing blood work.
