Uy, sorry to hear you're feeling off! Honestly, a few of us moms experienced nausea or stomach upset with Obimin Plus too, siguro kailangan mo lang i-take it with food or right after meals, or maybe try taking it before bedtime instead kasi mas okay ang tyan natin pag natutulog na. But since this is your first pregnancy and gusto mong maging sure, I'd really suggest messaging your OB about it, baka may ibang brand or timing na mas okay sa system mo, or baka may advice sila on how to take it better!
