38+4 pain in stomach

Adina • I`m 24 with a 2 year old boy and another on the way. Married for 3 yrs.
I was at the grocery store and everything was ok then all of the sudden my stomach started cramping out of no where & I kept getting these sharp pains, especially near my naval that forced me to hold my stomach & stop walking. What is this? I was so scared I thought I was about to go into labor. It was very painful.
