Am I going to get suspended?

Friday-someone took my phone in cl and sent a ual message to one of my friends.One of the administrators took her phone and read the texts and saw what mine said.Three other of my friends were texing her ual texts and they got out of school suspension.Idk who took my phone and i doubt that my parents or the administrators will believe me.The texts are deleted off of both phones now but the administrators already saw the message wrote down my name and the message info.Can i get suspended? my parents wont believe me and theyll kill me if i get suspended
