Baby rib part?

Hello, Im so worried kay lo is it normal na hindi pantay yung ribs nya? Like sa left side lower part ng ribs is paranv patusok/paultaw I dont the other term. But unlike sa right side parang okay lang pero kapansin pansin saakin yung left side nya. Do i have to worry na ba or not? I cant consult her pedia since Ncov19 . What should I do now?
