Muntah lagi

Hi mommies, during my first trimester I mmg had terrible nausea, vomit, gastric and heartburn. After going into second trimester , everything tuned down. Now still at second trimester but kat penghujung 6 months and I start balik vomit, gastric , heartburn and sendawa berpanjangan. Is this normal ? Is there anything I can do ? I hate seeing food dah, just feel like vomiting seeing food.
