I have been seeing so much conflicting information about fetal heart rate I am curious if anyone else had an ultrasound done at 9-10 weeks and also have a high fetal heart rate.
Someone posted this chart but I don't know the source. I was told that 140-180 is normal and 188 is out of the normal range so my doctor is recommending that I see a fetal cardiologist. I hate unnecessary worry because I actually think that 188 may not be that unusual (at least based upon some posts I've seen on here) just curious others experience...
