Heart burn/ indigestion 12 weeks

Have terrible heart burn and indigestion, every time I eat I feel like it’s just sitting there in my throat it’s horrible and 9 times out of 10 I’m constantly vomiting because of it! I feel absolutely awful 😩 nothing seems to be helping! I’ve tried rennies, gaviscon, eating ice-poles, sooking ice-cubes, drinking milk. Any other things I could try?
