Rib pain

leah

I'm 28 weeks pregnant & was sitting on my bed eating soup. Then I get this random pain in my ribs below my chest. It was a very sharp pain. I could not move at all, couldn't take a deep breath. Nothing! Eventually I pushed myself to get up by sliding off my bed and I got up to the wall and reached my arms as high as I could and it relived the pain. Anyone know what this pain was?
