Placental maturity at 22weeks

Hello po! Is it okay lang po ba na ang placental maturity ko ay GRADE II na at 22wks of pregnancy? Is it too early? Sa Saturday pa po kasi ang follow up ko sa OB, and I'm a bit worried lang po..baka po meron same case like me? How was it? Hope someone can enlighten me. Salamat po! Have a blessed pregnancy journey to all of us.🙏🏻❤️#firsttimemom #placentalmaturity #22weekspregnant
