Hi, im 8weeks an 3 days pregnant, I had an ultrasound today,... The heartbeat was at 150. I was wonderen if my chances of haven a misscarriage remain the same or am I less likley too becuz there was a heartbeat??? Im jus curious cuz I had misscarried almost a year ago,they couldnt find the heartbeat..And i've been praying that everything is ok and that the baby is healthy this time around, but I was jus curious.
