when did you hear baby on your fetal Doppler?

Madison • Me and my husband are parents to a beautiful baby girl💓
Tomorrow I will be 9 weeks. I search for my baby's heartbeat every morning and still can't find it. I see women that find it at 8 weeks 2 days and I still can't find mine. Should I be worried? I'm crying my eyes out. I'm someone that needs that reassurance, I worry about my baby daily I just want him/her to be okay and healthy
