My periods usually last about 5 days.

This week, my period started right on schedule but stopped after 2 days of flow.

I have not been under more stress than usual, my diet has not changed, I have not been having unprotected sex and I have not had any extreme lifestyle changes.

I'm in the middle of exams (can't be exam stress, I haven't been studying that much)and therefore do not have the time to see a doctor until the middle of this month.

I want to know if this could be a symptom of something more serious or if this stuff just happens.

Any comments will be greatly appreciated.

thanks
S.
