Aw, first time mom jitters! Honestly, baby size at 32 weeks can vary a lot, some babies are bigger, some smaller, and that's usually totally normal, but your OB is really the best one to tell you kung okay ang development ng baby mo based sa actual ultrasound and measurements. A few of us moms in my circle worried about the same thing, pero ang doctors namin lagi namang sinabi na as long as baby is growing consistently and within the expected range for that gestational age, walang alalahanin! Do have your doctor check and explain kung saan exactly ang baby mo in terms of size, kasi peace of mind lang yan para sa inyo both, lalo na first pregnancy mo pa!
