I went for a sonogram at 8 weeks and 6 days. The baby's heart rate was 218. I went for a regular appointment at 11 weeks 2 days and the doppler said it was 193. I am only 25 so I wasn't worried about chromosomal disorders but now I am. Should I go to a bigger and better hospital and get some tests done based on this heart rate? My hospital apparently can't even do a NT test. Am I overreacting on this?

160 BPM for a fetal heartbeat according to my information is high; but 2l8, well, too high and can indicate oxygen deprivation and any number of reasons. Yes, go to a better hospital and get some tests done.
