Uy, this is something talaga you need to bring up with your OB/GYN, they can give you proper guidance based on your situation, lalo na kung nag-aalala ka na. From what a few of us moms talk about, it's mostly about prenatal care, proper breathing during labor, and listening to your doctor when the time comes, pero seryoso, your OB is the best person to discuss prevention strategies with you personally. Kaya punta ka sa check-up mo at tanungin mo directly, okay? They'll know exactly what's best for you.
