I'm really stressed. I was in the hospital for 8 days when I was 28 weeks pregnant for contractions and baby boys heart rate dropping. I came in yesterday to the hospital and the same exact thing is happening again. My baby boys heart rate will drop and stay dropping for about 2 mins and then start coming back up. (By this time all the doctors are in my room) I'm just really worried 😭
