Bcos you ate alot hence that uneasy feeling and nothing to worry about as bloating is very normal in pregnancy. Never eat for 2 just because you're pregnant. That's how many pregnant women gain excessive weight & may have big babies. Eat smaller meals but frequent. Don't worry your baby will not go hungry in your womb if you eat small meals.
Baby won't be harmed because you ate a lot 😅 don't worry.Bloatedness is common and should be temporary. You probably feel better now already
