Having sex @ 9months pregnant

Super weird question lng po. (Or baka para sakin weird) currently 9 months pregnant and inadvisesan na ni doc na magDO para magopen cervix pero mejo natatakot kasi baka masakit since low sx drive ako during pregnant and baka di magLube. Possible kaya iE-jack muna then ipasok nlng once lalabasan na? Serious question lng po talaga. Thank you
