Home Fetal Doppler

Hi, mommies! Ask ko lang if sino gumagamit ng home fetal dopplers sainyo? May clearance ba ng OB nyo? Ano sabi ni OB nyo regarding fetal dopplers? Safe ba daw? If yes, ano brand yung gamit and trusted or recommended ng OB nyo? PS, I trust my OB so muuuuch and as per her advice, di sya necessary. Pero you knowwww, di maiwasan maging praning lalo I miscarried na last year. Parang gusto ko magpacheck up weekly haha para lang makasigurado na ok ang lahat but of course di naman pwede Help please, thanks! 🤗
