Frequent burp with acidic taste

I did encounter that, it sounds like gastric/ reflux. You can try to ask if your gynae could prescribe something to relieve the discomfort. For me I had antacid and it did help. As I didn't like the taste of the antacid, I did try to cut down on food and drinks that may trigger the symptoms. E.g. Caffeine, spicy, sour, rich/ fried food. Also, eating earlier, not lying down too soon after eating and managing my food portions helped.
