Nausea at week 23

Hello mummies, do you feel nausea or vomit after eating from week 23 onwards? My first 3 months were really bad as i kept vomitting everything i ate. But it got better when reaching my 2nd trimester. But now im at week 23, i started to vomit my lunch and my dinner again. Being the first time mum, im worried if its not normal. 😔
