Chance of miscarriage

I am so excited about having my baby! I literally can't even explain how blessed we are, wasn't planned but still so happy! But I see often on here about women miscarrying & I couldn't even imagine the pain they feel. I get scared that it could happen to me because they stats are like 1 in 6 pregnancies end in miscarriage but those include chemical pregnancy when women don't even know they've conceived. So up until I was 7-8 weeks the thought crossed my mind at least once a day, which was sad & disturbing because that's not what I wanted to be thinking about. I got my first ultrasound at 5 weeks 6 days & thankfully saw the heartbeat. At 7 or 8 weeks though I read once you see or hear a heartbeat your chance for miscarriage drops to 3%. Knowing this fact really helped ease my mind & now it's rear I think about it! I just wanted anyone worrying to see this & maybe it will help a little! God bless! 👶🏼💕😍👼🙏
