Membrane Sweep Details?

Taylor • Wife 💍 One early miscarriage Dec 2018 👼🏻 Currently due with our rainbow baby 8/11/2020 💙💖

Hi ladies. So I’m 38w today, FTM, 1cm dilated, cervix is still posterior. My doctor said we could do a membrane sweep next week if I wanted. Not really sure what to do. Any experiences, advice, pros, cons? All the details please!
