Aww sis, totally get the nausea! A few of us tried different brands, one of my mum friends swore by Elevit kasi mas mabait sa stomach, and another switched to a gummy version kaya mas swak sa kanya. Since you're already on Hematate FA and calcium, definitely bring it up sa OB mo because they know your specific needs best, pero malaki ang chance na magbago lang ng brand or timing (like taking it with food or before bed) ang solution. Maraming options out there, so don't worry, makakahanap kayo ng perfect fit para sa iyo!
