Hindi ka nag-iisa, sis! A few of my mum friends had grade 3 placenta din around that time, at honestly nakapanganak sila ng normal at healthy babies, one even went pa up to 38 weeks without issues. Best thing talaga is to follow up with your OB closely para makita nila how baby is doing, kasi every pregnancy is different, pero encouraging talaga yung stories like yours na nag-deliver ng maayos kahit ganyan. Fingers crossed for you, mama!
