Skipping heartbeat

Kelsey
So I'm 16 weeks pregnant and we found out my baby is a girl (Kensley Mae)...while we were having the ultrasound I heard the baby's heartbeat and it was skipping. I'm friends with the ultrasound Tec so I asked her does that sound weird and she said yes but not to worry till I talk to the doctor...so short story, the doctor told me not to stress and hope it will fix itself before or shortly after birth...I'm trying not to worry but can't help it! Is anyone having the same situation ?
