I have been reading online that babies should have a heartbeat of 160bpm to be considered safe. At my private scan (8 weeks) the technician said they couldn't tell me the speed. Then at my scan with the EPAU (8+5) the midwife said it was too early to tell although there was still a heartbeat. I've seen online some people saying they found out how many beats from 7 weeks+ so I would like to know whether I've been told this to keep me from worrying? My next scan isn't for 3 weeks or so.
