Yung mucus plug is that thick, jelly-like discharge na nakablock sa cervix mo during pregnancy to protect baby, so yes, yan ang makikita mo! Pero mama, since you're at 39 weeks with a scheduled CS, you really need to confirm with your OB right away kung okay lang ba mag-VBAC given your situation, kasi may considerations talaga especially if may complications or kung anong reason ng first CS. A few of us tried to push for VBAC din after CS, but it's super important na ma-check kung eligible ka talaga and kung safe para sa baby, don't want any surprises this close to delivery, alam mo? Best to message your doctor ASAP para ma-clarify ang plan, whether you'll proceed with CS or if VBAC is still an option. Sending you strength, mama, alam mo yan nerve-wracking ang mga decisions na ito!
