Beta its very common in pregnancy, the hormones cause it. For mild burning try eating small meals and a little cold milk used to help me. But if its severe or constant do mention to ur doctor.
Hormones are the main reason, they slow down digestion. Watch your trigger foods, mine were tea and fried stuff. And dont go straight to bed after meals, keep a gap. If it stays bad ask ur doctor for something safe.
My gynac explained its mainly the pregnancy hormones relaxing the valve at the top of the stomach, so acid comes up easily. Progesterone basically. Thats why even early on you can feel that burning even before the bump shows.
Actually its the hormones plus the growing uterus pushing things up later. For me spicy and oily food made it way worse, so I cut down and ate dinner early. Helped a lot yaar.
