Oo normal yan! A few of us felt na parang mas nalalampasan kami sa lamig during pregnancy, kahit mainit pa naman sa labas, parang ang body mo ay gustong mag-adjust sa lahat ng changes, lalo na ngayon ka pa lang early in your pregnancy kaya sobrang sensitive ka. Check with your OB just to be sure walang anemia or kung normal lang talaga sa hormones mo, pero honestly a lot of first-time moms go through this din, so you're not alone! Keep yourself warm lang with light layers, and drink plenty of water, sometimes dehydration makes the chills worse.
