6w4d could see but not hear heartbeat

Went in for a 6 week appointment today and got to have a transvaginal ultrasound done! I thought based on my cycle length that I was 6w1d but Baby Bean is measuring closer to 6w4d. The ultrasound tech said my uterus has a bit of a tilt to it so it was hard to get a good picture and hear the heartbeat but we could certainly see it! How many of you have been able to hear the heartbeat at that point? I feel like it was the same situation with my daughter at 6 weeks. We could see it but just couldn’t hear it. Going back in two weeks for a re-check.
