Period is getting late :(((

Anna

So I’ve been having some stress about the exams of course, poor eating, and also a fever for like 5 days (2 weeks ago)

And I’m wondering if that could have caused my period delay? Cause now it’s late by 3 days (should be 4th already). I’ve had protected sex like a month ago also.

Now it’s like an extra stress for me, because usually my period was super regular, so pls did anyone had something like that? Help
