Ay, good na nag-schedule ka na ng OB check-up bukas!
Honestly, those are super technical terms na mas better i-explain ng doctor mismo, AFI at DVP ay measured differently, and ang normal ranges ay depend talaga sa how far along you are. A few of us moms tried asking online, but kina-confuse lang kami more, haha! Your OB will explain it clearly bukas and show you the ultrasound results, so you'll understand better. Wag mag-stress muna, you're doing the right thing by checking in! Let me know what doc says, okay?
