I'm in second trimester and still have bloating. Sometimes I can't even sleep properly 😟Then I take a Ayurvedic medicine called Pudin hara, made of mint. Sometimes when the bloating is too bad I drink plain soda. Some say it increases bloating but in my case it helps me burp and then I feel better. Food wise I don't know what triggers me exactly. I use ginger (crushed, so that it gives max juice) in food. And also drink ginger honey tea. Helps to some extent
