Hyperacidity during 1st trimester

Who else experienced hyperacidity sa first trimester nila? To the point na ang suka ko puro watery na feeling ko acid since mahapdi at feeling ko nasusunog lalamunan ko dahil sa sakit. I have consulted this with my OB na and sabi niya normal lang and take gaviscon but gaviscon is not working for me. Any advice? #firstbaby #pregnancy #advicepls #pleasehelp
