Uy, normal talaga yan sa pregnancy, lalo na around second at third trimester when baby is growing fast! A few of us mums experience na parang sobrang gutom ka kahit kumain ka lang, tapos midnight cravings hit different, one of my mum friends swears na dahil sa hormones at ang bilis ng metabolism mo when you're pregnant. Pero kung talagang intense na or may ibang symptoms na nakakakuha ng attention mo, better check with your OB lang para sure, okay?
