I am 20 wks today and went for my anatomy ultra sound... as the tech is doing it she is telling me everything is normal...then she says the heart rate is extremely low it's at 80 and should be at at least 120...... she doesn't kno y it's so low... called up labor and delivery at the hospital so so I can go and see if I can get an echocardiogram on the baby's heart...so now I'm really scared... all my blood work was normal and i feel her (it's a girl) move often...whats even more scary is that I get there and since it's the weekend there is no pediatric cardiologist on to check it... at the end of the day I have no real answers and have to wait till next week and now I feel cramping.... trying not to stress but I can't help it...has anyone else been thru this
