Hey mama, yan ay pretty common naman talaga, some babies just develop their belly/organs slightly ahead of their head, lalo na if you're eating well and baby's getting good nutrition! A few of us mums went through the same thing and our babies turned out perfectly fine, pero mas safe pa rin na i-mention mo yan sa OB mo next visit para sure lang, especially since iba-iba talaga ang development ng bawat baby. Wag mag-alala masyado, most likely okay lang yan but your doctor can give you peace of mind better! Take care and fingers crossed for a smooth delivery, mama!
