Late period and refuse to think the latter!

As embarrassing as this sounds, my period is 3 days late. I will admit that I had been previously intimate with my long-distance partner last month (Late September), shortly after my last period. — We stopped using protection a while back and I am no longer under family’s insurance. 😭

Someone give me hope that my oven isnt baking and this is possibly due to stress? I’m not showing any pregnancy symptoms at all, and I am in college after all. My monthly has been delayed due to stress before but that was years ago.

Other Info:

Test? Not yet

Usual cycle duration? 5-7 days

Last Cycle? Sept 19 to Sept 24th
