Hi mama! Anterior placenta means yung placenta mo ay nakaposisyon sa harapan ng uterus, and Grade 1 previa means ito ay malapit lang sa cervix pero hindi pa fully covering it, which is actually good news kasi marami sa amin na ganyan and normal labor pa rin, walang problema. Kailangan mo lang i-monitor regularly with your OB para sigurado na hindi mag-progress into something more serious, pero karamihan ng cases like yours ay okay lang by delivery time. Some of my mommy friends had the same thing at nag-normal delivery pa rin sila, so wag ka mag-alala muna pero definitely follow up sa doctor mo para sa peace of mind, okay? Congratulations sa first baby!
