Sex at 37weeks

Hello mommies! FTM po ako and really aiming for normal delivery. God's willing! No sex po kami ni mister since week 5 of pregnancy, now po that I am at my 37weeks tanong ko lang kung pwde na ba mag sex again? Makakatulong ba ito para ma ready ang pem2 or ma soften ang cervix natin?? High lying grade 2 po ang placenta ko and cephalic na si baby. Sana po ma notice. Thank you
