I agree about the change in the HB quickly. I had to go the hospital & was hooked up to a heart monitor, so got to listen to baby's HB the entire time I was there. It was constantly changing with me just sitting there drinking some water.
I'm 31wks and my sons heart beat is 152
The baby was probably just moving. At this stage you would know if there was a twin. My first hit a growth spurt around 28 weeks and measured bigger the whole rest of my pregnancy. Which is why I was induced at 39 weeks. They didn't want him to be too big, I wouldn't have physically been able to birth him.
My baby girls heartbeat changes every time my doctor checks it because she moves around so much. My doctor just waits a couple minutes for her to calm down and uses that number
Heart rates can change by the second, especially if the baby is really active. It is no different from your heart rate increasing from movement
My babies heartrates have always changed lots in one sitting... Anywhere from 140 to 160, my midwife always just writes the average... If they move their heart rate can go way up... So to me what you're describing is really normal...
What no way that is wonderfully shocking
I would think they would likely see another baby in an ultrasound if there was more than one?
