Ay, alam ko yan! A few of us moms actually go through this, ang vitamins kasi minsan talaga nakaka-nausea lalo na pag walang pagkain, so maybe try taking them with a full meal or after you eat something substantial instead of on an empty stomach. Since ang loss of appetite mo ay tumatagal na at nag-worry ka na, mas better if you check with your doctor para sure kung may iba pang dahilan, or if kailangan mo ng different type of vitamins na mas gentle sa stomach mo. Alam mo, hormones and pregnancy stuff can really mess with your tummy, kaya wag kang mag-assume lang, let a professional make sure lahat okay with you and baby.
