I was on day 36 (which is close to average for me). I started bleeding. But not the normal amount. It was bright red and somewhat thin.

4 days of it. Then nothing.

No cramps happened, no breast tenderness, no bloating.

I've never had short periods before.

They're normally 7days of bleeding, heavier than that, and full of cramps and tenderness.

Wondering if I should go see a doctor or if this sort of thing can just happen?
