I don’t know what to do 🤷🏼‍♀️

(I’m 14) So about 3 months ago I skipped my period , I blew it of off and continued on my regular cycle, but the 12th I was supposed to get it and I’ve been waiting for it and I think i skipped it again🤦🏼‍♀️ idk if I’m doing something wrong , or if there is something wrong. Anyone know what’s wrong with me??
