Hindi normal yan, mama, kahit prenatal vitamins, dapat hindi ka masakitan ng sikmura after taking them. A few of my mum friends nag-experience din ng ganitong problema, kaya nag-adjust sila ng timing or kinain nila with food, pero dapat talaga i-check mo ito sa doctor mo para sure na okay lang. Baka kailangan mo ng different brand or dosage, o maybe kailangan mong kainin ng more substantial food habang umiinom ng vitamins, pero yung best advice talaga is from your OB kasi 5 months ka na at importante na sigurado kami na safe lahat for baby.
