Am I going to have my period soon?

So, I haven't started my first period yet and I have small breasts. Though, I do feel aching in my lower stomach. Am I going to start soon? My breasts are not that big and they are pointy. I wear a bra because I feel insecure. My mom started her period at 14. PLEASE HELP?! When I was younger back then, I was playing seating area at the arena. I hit my vagina & it hurt so bad. I don't really remember. Sometimes I think I wont start them. I'm scared. I've also started having pubic hair when I was 12. My breasts didn't start to grow until I was 13-ish. Are my boobs going to grow more? Am I going to have my period soon? Oh yeah, I don't wear a bra when I'm sleeping. I heard when your braless at night, they grow much more faster. Every girl in my class have already had their period and have boobs now. I'm 14 years old. I am in 8th grade.

Thanks.
