For those who have had early ultrasounds, when did you hear the heartbeat?

M.

I’m going for my US Friday and I’ll be 5w5d. Really

Hoping we hear the heartbeat but I know it may be a little too early. I see an RE so that’s why I go so early. They’ll want to see me every 10 days until I’m about 10 weeks or so. When was the earliest you heard the heartbeat??
