Fetal HR 8w3d fluctuating??

[Hannah0101]

Hello
I went for an early ultrasound today and the baby looked good and is measuring 3 days ahead of what I expected based off my LMP. There was a strong heartbeat which we got to hear however initially it was 114. The sonographer then measured it again as that was on the lower side and it was 183 which was a big jump up. The sonographer said this is normal and wasn’t concerned at all. Am I worrying for nothing?
thank you!

Understand your concern but if sonographer said all normal take them at their word they don’t lie

If somographer said fine, why would internet randomly know otherwise? I’ve never been told the baby’s heart rate at any scans, private or NHS
