Early ultrasound

Kr

We had a miscarriage at the beginning of October and just found out we are pregnant with our rainbow baby. I’ve had a couple of blood draws to see what my HCG levels are and the first was 1380 and the second was 2791. My doctor said my levels were rising “appropriately” but I’m still so nervous/anxious. We have our first ultrasound in a few weeks and I’ll be 7weeks along. Has anyone had an ultrasound that early and were able to hear the heartbeat?
