I'm tried of being in pain?

I went to the hospital because I was getting really sharp pains on my lower stomach and they told me it was normal since I'm pregnant but the weird thing is that I've always kinda had that sharp pain even before I was pregnant just not as bad as it got. 
It hurts when I cough or sneeze or laugh even when I pee. It hurts for a while and then it stops. Does anybody know anything about this?? I've been to the hospital for it twice now and they say everything looks fine but it hurts a lot .
