Fetal Heart Rate (New Mom)

Im new to this and i was wondering is a heart rate of 185 normal for being 6 weeks 5 days ? I’m currently 7 weeks as of my last scan to date my pregnancy after conceiving right after a miscarriage. I just want to know since the ob/gyn didn’t say anything about it and I’ve tried looking it up but nobody around that time have ever had a heart rate that high unless they where farther along. So I’m confused.
