LATE BY 2 Days

I’m technically late by a day or two. I know I’m not pregnant because I’m very causious and also because we haven’t had sex besides 1-2 days this month and again we’re very cautious. HOWEVER, it’s been a very stressful month of April due to finals, tests, papers and all that shabang due for school along with losing a family memeber 2 weeks ago. I’m very stressed and can’t seem to relax. I know stress can delay a period so I’m convinced that is what it is. I can’t help to stress because my period is late but I know stress is what is causing my period to be late. Any tips on how to relax or induce my period??
