baby's heartbeat ❤️

Judy
Im 11 weeks 6 days heard baby's hb today first time at first doctor couldn't find the hb so he got the specialist and he found it it was 150 they said baby is hiding in one of my arteries? Does that make sense??? I asked my doctor if that was normal and if baby is ok and he said yes baby is fine... has that happened to any mommies before???
