Heartrate 89 -6 weeks 2 days

Laura • 4 miscarriages, one living child, pregnant again.

Hey ladies, I need some reassurance. Last week I got the best news ever -there was a heartbeat. I have had two miscarriages and there has never been a fetal heart beat. When I got the news I misread the heartrate thinking it was 99. Today I looked back at the message from my dr and it said 89. Of course I have googled and it says 64% of pregnancies with heartrate under 90 end in miscarriages. I am ready to cry, my first miscarriage was a missed miscarriage at 7weeks 5days. I didn't have a scan until I thought I was 10 weeka so I don't know if there was a heartbeat this early on. Can anyone please tell me their experience with a low heartrate in early pregnancy.
