Some times it feels like i have to go to the restroom?

Some times it feels like i have to go to the restroom so i go, but i cant.Then i get ready to go somewhere even if its a block away, i have to hurry up and rush to the rest room and its totally embarring, i fells like im going to go in my pants which is gross but true.At first i thought it could be the flu or something but its been going on for about 5 days now and i cant go anywhere with out having to rush to the bathroom. I dont no what it is but if someone has ever had this happen to them and can tell me whats going on i would really appriate if, i just wanna be able to actually go to and not have to worry about going in my pants?
