Mama, normal lang yan, parang lahat ng friends ko nag-worry rin around 39-40 weeks dahil excited na mag-deliver pero baby pa rin ang bos haha! The cervical mucus is a good sign na your body is preparing, but labor timing talaga talaga unpredictable, some moms go naturally within days, some need induction at 40+ weeks. I'd definitely check with your OB about what to expect next, especially if you have other signs like contractions or fluid leakage, para sure kayo both okay. In the meantime rest, eat well, at be patient na lang, baby will come when ready!
