Getting too full

Currently 31 weeks and I can barely eat! I want all the food especially in this last trimester but I physically can’t eat it because I get so full and immediately get heartburn. If I push myself to eat it anyway then I get a sore belly in the morning and I don’t sleep all night long. I can do small wraps and salads and small snacks but not big meals. Its getting Cooler out and I want all these hot and hearty meals but it hurts physically to eat it. Anyone going through this? I just keep telling myself 2 more months!
