Fetal Arrythmia

Dominique
Does anyone have experience with this? I am currently 15 wks, 5 days. We noticed the irregular HB on Saturday during my little girls gender reveal. We listened to it on Doppler Sunday and the doctor listened this morning and her heart still skips. The HB is still in the consistent 150's even with the skipped beats. I have an anatomy scan scheduled next week to screen her heart. They wouldn't do it today because they said she is too small at 15 weeks. I'm sure my angel is fine but it still scares me. Any other mothers have experience with this?
