I'm 17, a virgjn and, my period is pretty much always regular. Im now ten days late for my period. Seven days ago, I did Mastrubate with a hair brush handle ( it was clean and everything) but about ten minutes afterward I got really light headed, nauseous, shaky, I got the chills, and a really intense pain down there. It went away after a half an hour or so, and the pain completely disappeared after a day, but I'm now concerned that maybe I did something that stopped my period? (These past few days I feel like I'm getting my period but never do, achy breasts, a little cramping, and bloating.)
