Hi! Grade 2 placenta at 32 weeks is generally normal, a lot of us saw the same thing sa aming ultrasounds at that point, kasi as pregnancy progresses, the placenta naturally ages a bit. But honestly, ang best person to ask is your OB mismo since they know your full medical history and can see your exact ultrasound results, so make sure to clarify with them kung may concerns sila or kung totally okay lang everything.
