Period blood or blood in urine?

[Davespecifico]

My last period ended. I had about a week off. During that time, I went from sedentary to exercising vigorously for 30 mins a day.
Since then, every time I’ve gone to the loo, the tissue has had pink/ brown colouring, like the start or end of a typical period.
Would this be due to exercise or should I find out if it’s blood in urine? I’ve had 2 weeks of it.

Well it's very simple to establish if it's vaginal- insert a tampon and remove it and look at it. If it comes out clean then try weeing into a glass and see what that looks like. Although blood in urine isn't always visible if it's a small amount.

Might be a stupid q but are you eating beetroot?
