in pain advice please

Gayle
im 15 wks and just got home from work, lay down on the bed and got sharp pains in my belly all around my belly button area. i couldnt roll over it hurt so much. Still hurting now a good 15-20mins later and the only relief is when is push my belly out like i'm making myself fatter.
Do you think its anything to worry about or just my body having a stretch??
