Bein pregnant

Has anyone else experienced pain in the lower part of the belly when you’re pregnant if so, please explain what you did to prevent that please? I’m 7 months along n I’m always comfortable in pants that are stretchy but I haven’t warn any prego pants cause I was so comfortable but since I’ve gotten bigger I’ve been thinkin about wearin some prego pants for work. So what I’m askin is….is it normal to feel a little bit of pain in the belly from gettin bigger or do I need to be concerned about it?

Please no negative comments
