Ay oo talaga, normal yan sa first trimester lalo na kung first time mom ka! Ang nausea at loss of appetite ay super common sa weeks 8-14, kaya don't worry too much. Try eating small frequent meals instead ng three big ones, and stick sa bland foods muna like crackers, toast, or broth, yung makakababa lang sa tiyan mo without triggering the nausea. Ginger tea or lemon water also helps sa iba, pero syempre if it's getting worse or you can't keep anything down at all, better to mention it sa OB mo just to be safe, because they might have tips or meds specifically safe for pregnancy.
How are you managing naman overall, kaya ka pa mag-function sa work or everyday stuff, or is the nausea really heavy?
