Ay, first-time mom ka pa, kaya understandable ang tanong mo! But honestly, this is something na kailangan mong i-ask directly sa OB mo during your next check-up, super important ang cervical changes during pregnancy, kaya dapat siya lang ang magbigay ng go-ahead based sa your full medical picture. A few of us moms always check with our doctors about these things dahil bawat pregnancy ay different. Wishing you a healthy pregnancy!
