Fast heart rate even at rest and blood in wee (is this normal when on period?)

Hi. I'm feeling quite weird lately. I have quite a fast heart beat even at rest and just peed blood (have started my period). Yesterday i felt like i had flu with headache, temperature, aches, nausia. I quite often get cold symptoms around my period, but not normally that bad. I took ibuprofen (2 200mg tablets every four hours) which helped, plus an enchinacea cold/flu tablet, and just rested.

Is it normal to have these symptoms just before a period?
