Lower tummy pain after eating

Im currently in 2nd trim and sometimes i get either pelvic pain/round ligament pain or pain below tummy after eating or if im too full, when tummy is hard. Is it normal and common for preggy mummies ? As it always gets very uncomfortable when im full cs my stomach will be extra hard and kind of expands more, which feels like there’s more weight on my tummy 😣 #FTM
