Uy, mama, I need to be honest with you, this is something you really need to discuss directly with your OB or go for a check-up soon, ha? An open cervix at 12 weeks is something that needs proper monitoring from your doctor, hindi lang based sa stories from other moms. I know maraming possibilities ito and it can be scary, but your OB will know what's best for your situation specifically, whether you need extra check-ups, activity restrictions, or anything else. If you're not comfortable with your current doctor, definitely okay lang mag-transfer, pero make sure the new OB knows your full history right away. Hugs, mama, you're doing the right thing by being proactive.
