Currently 16 weeks and all day my mid chest and right side of my chest has ached. I keep burping and having a bad taste in the back of my mouth, and I feel like there's a bubble stuck in my throat that I just can't burp out. I've never had heart burn or indigestion in my life. Is this what it feels like!? I've eaten really bad greasy foods for lunch today as well. Any advice for symptom relief???
