Please help

Ever since I've found out I was pregnant I keep getting these severe pains in my abdomen no blood. It litterally hurts so much I start to cry. It doesn't last long and it feels like I'm being stretched in the inside. I don't feel like it's suppose to hurt this bad during pregnancy. I'm not bleeding or anything and it's not all the time. Just randomly. It seems like mostly when I have to pee. Which is a lot... Please help.
