Fetal Doppler

Monica • Excited to meet my baby girl👶🏽🎀😍
I recently bought a fetal Doppler and it took me about 3 days but I finally found my baby's heartbeat!!! (Soooo exciting!!!!) I was searching right below my belly button...guess where the baby was.....right by my pubic bone. I'm a first time mom, is it normal that my baby is that low yet?? I'm 15 weeks and 5 days.
