Hello all!

So I had my first ultrasound at 6wk 6 days and baby had a heartbeat of 129 💕💐 I was a little worried because it’s so close to 120 and every progressing day keep getting a little more nervous. I’m about 7wk 5 days and have been hearing about fetal Doppler’s. I’ve heard mixed reviews on how safe/effective they are and am hoping you can provide some insight. I can run to the doctor and request the heartbeat every week but I don’t want to continue to be anxious every day if the baby’s heart is still okay. I had a miscarriage at 4 Weeks last year so everything has me nervous

Any advice from woman who have used them?
