When is heartbeat detectable?

So I had a complete molar pregnancy in Feb of 2019 and I just found out we are expecting! I’m literally only 4 weeks + 1 right now so clearly too early for an ultrasound. I messaged the doctor to see when I should schedule my first appointment and she said around 7 weeks. I’m anxious because I didn’t know I was miscarrying last time until my first ultrasound at 10 weeks so I don’t think I’ll be able to chill out until I get that first look. I was wondering if it’s even possible to hear the heartbeat around 7 weeks along? Your experience?
