Mine was 175 & I thought that was fast, but my doctor wasn't concerned. If your doc isn't worried I wouldn't worry, but if it puts your mind at ease make sure to ask him/her about it.
I'm sure your doctor would have told you if it was way too high and beyond the reasonable bpm. and rest assured your baby's heartbeat will actually slow to an extent the larger they get, and the more they develop. Ask your doctor if you're concerned about it, they will be able to let you know when or what would concern them.
I Was If It's Higher Than 170 It's A Concern? My O/b Said That During My First Ultrasound. Every Doctor Is Different
My baby's has been 184 every appt Ive had 3 and am 13 weeks. Its normal. Dr said it'll slow as baby gets bigger.
Did the doctor say anything about it. Its seems high to me but I am not a doctor by any means. If no one mentioned it I wouldn't worry about it
