Aw sis, this is totally normal, every pregnancy is really different kahit third time na, and honestly ang hormones ay basta wild talaga ngayong beses! A few of us mums noticed na ang third pregnancy namin parang mas intense ang morning sickness at food aversions compared sa first two, so you're definitely not alone dito. Since you're struggling so much with eating sweet foods at ang smell sensitivity ay affecting your nutrition, I'd really suggest checking with your OB about this, they can help you manage it better and maybe suggest alternatives na kaya mo kainin without the vomiting. In the meantime try eating bland, salty snacks instead (like crackers or fried fish), ginger tea works wonders for some of us, and maybe stay away from the diaper area ng baby mo when you're feeling extra sensitive na haha. Kaya mo yan, mama, third trimester lang 'to and it will pass!
