I have an exam in a few days and I just can't concentrate. Like I'm trying so hard to study for my exams and I always end up doing something else. So I'm so stressed about being unable to get it together.

I searched online whether difficulty concentrating is a PMS symptom and it turns out it's possible because I'm a few days late on my period (due to excessive amounts of stress for the past few weeks).

Has anyone experienced this? If so, how did you deal with it?
