Period?

Hey guys!! I feel like I can talk to you about anything. So I will say I only use this app for period related items. I am 13 and going into 7th grade. I got my period during the being/middle ish of 5th grade. Its due today. ((currently 4:50 am )) I haven't got it yet and I haven't gotten any signs of it coming. I have masturbated but nothing other than that. Although I was with my boyfriend ((ex)) sometime last month and I got my period but it lasted 4 days. He made me very uncomfortable when I was with him because he had touched me "down there".and he texted me and said he jacked off and then tried to finger me. Thats why I broke up with him. I know that you can't get pregnant by someone found that. Right?  Anyways  I was wondering if any of you knew if its normal that my period hasn't came yet.
