Was it definitely baby’s heart beat? Your heart rate will likely be about 88 so it could be picking up yours. Only because if it was baby they would have wanted to delivery them asap? Seems weird for them not to act on it especially with your history. Definitely query it x
I'd go back. I feel like they always tell you something different depending on the person. X
Isn’t the whole thing that when you lie on your back, you compress blood flow to the baby or something like that which is why they tell you to sleep on your side and lie on your side from a certain point in third trimester ?
I wouldn’t accept this, 88 is low I’d go back and ask for further monitoring! X
