Oo normal yan first trimester, lalo na kung first pregnancy mo! A few of us mums nag-kwento na sobrang sarap daw ng pagkain tapos suddenly hindi na, haha, it's the hormones doing their thing. But if it's really severe or you're not keeping anything down, definitely check with your OB para ma-rule out severe morning sickness or other concerns kasi importante na kumain ka ng nutrients para sa baby mo. Hang in there, mommy, usually nag-improve na ito by second trimester!
