Hi I'm 16, my period is 12 days late but I haven't had sex. My boyfriend haven't done anything for me to be pregnant so I wouldn't say it was that. For about 3 weeks I've been under a lot of stress with school and family matters , I know periods can be late because of stress but this is my second day getting dizzy around the same time, I think. I'm very worried. I know it could be anxiety/stress which I've been working on but I wanted a little input on what it could be. Could it be my period coming because my back has felt a little like it's coming.? Someone please answer ):
