Ay mama, honestly yan ang tanong ng maraming pregnant friends ko din! From what I've read and what a few of us have experienced, intimate time with hubby can help soften the cervix naturally kaya maraming OB ang okay lang dito, pero walang guarantee na ito magtatrigger ng labor or mag-speed up ng delivery, lalo na kung 33 weeks ka pa lang, maaga pa yan. Best talaga na i-clarify mo directly sa OB mo kung okay lang para sa inyo dahil every pregnancy is different, at sila ang makakasabi kung may any concerns based sa condition mo specifically. Basta safe lang kayo both and he's gentle, pero para sa peace of mind mo talaga, ask your doctor na lang next visit, alam mo naman paano seryoso ang OBs natin sa ganitong tanong haha!
