MASTURBATION I THINK?

Sorry to ask this but okay lang ba mag masturbate ang 5months preggy? Bawal kasi kami mag do ni lover, so para maka raos ako kasi sobrang taas ng sex drive ko lately im doing self masturbation nalang, im not using any toys, diko rin fini finger vagina ko, rina rub ko lang yung tingle, tas pag feel kong tapos nako i wash my private part, kaso parang naninigas yung tummy ko ng mga ilang seconds tas wala na, is it okay po ba 😥#advicepls
