7 week ultrasound

Andrea • Momma of 1 👧🏼 March 19- IVF-fresh transfer= miscarriage @8 weeks. July 19- 2nd IVF= 🌈👶🏼 Due 4/2!

Just had our first ultrasound today. Baby’s heart rate was a 105, which they said was average. But baby is only measuring at 6 weeks 3 days. We could hear and see the heartbeat. Anyone had this happen? Thoughts?
