I'm in my first trimester, and I'm experiencing some unusual abdominal discomfort, almost like a 'thepulu' feeling. It's a bit worrying. What could be the reason for this kind of feeling during early pregnancy?
The hormonal changes, especially progesterone, slow down your digestion process which leads to burps and gas. If it gets too uncomfortable, definitely ask your gynac for a safe antacid.
I had to watch my diet closely due to gestational diabetes. For belching, avoiding fried foods and keeping a gap between meals helped, but do check with your doctor.
