Little worried

I’ve been stress for awhile because of personal things in the whole month of August and with my anxiety and school starting my period has been almost a month late and my periods before that have been regular every month but idk if itsjust stress or also my diet because I’ve been eating more dif foods and certain parts of my body will ache

And now I get a sore pelvis and I’m not sure if my period is coming because I’ve been getting it lately and my thighs and sometimes down to my legs and stuff and I think I just had ovulation cuz there was some slight discharge but I could be wrong does anybody know if my periods coming or if it’s my stress as well
