Heart MurMur 😔

So some of you know I posted baby was a boy yesterday. I'm 19 weeks 2 days. I had my anatomy scan done yesterday. My previous ultrasounds or Doppler scans baby heart was VERY strong and normal and yesterday all of a sudden his heart started to skip a beat and I heard it. The Ultrasound tech took the photos to a doctor. He then asked for more and they scheduled me for another ultrasound in three weeks to specifically listen to baby's heart. Has anyone else gone through this? They said it might go away. In God's name I pray it does. Any advice ? ❤️❤️
