Do you have a pain in your vagina when your water breaks?

Im 7 months pregnant TODAY, so i am kinda freaking out, I just peed and i make sure its all out before i stand up but when i went back to my bed I felt a sharp pain in my vagina and then like not even 5 minutes later i felt wet and looked down and had a spot on my pajama pants the size of a small biscuit(best example i could think of) that was wet. im just kinda nervous idk if i am just paranoid but i just would like to know if any one experienced this when their water broke. please ANY advice will help!!
