29 wks preg with swelling on ribs?

i started having slight pain on my right ribcage yesterday which had bit of swelling on it and its very painfull like ive been punched there, havent felt baby move much at all but it may be because of the pain im in - it hurts even when i cough, is this a common thing in pregnancy or should i get it checked out and is it likely baby is okay as i have hardly felt her at all
