Hi! I am 19 years old, so here's my story first. I have my normal period and I take medicine to reduce pain but I notice that there's few blood coming out so after my 5 days my period ends. After a couple of days I have brown discharge and now its red(blood). So my question is, is this normal?

The brown discharge is normal, but having actual red blood after is not. It sounds like you have a hormone imbalance and need to be on birth control, or a different birth control.

How much red blood? Spotting during your cycle isn't unusual and there could be MULTIPLE reasons for it. Have you talked to your doctor about this?
