I'm 20 years old. I started my period on November 6th and now it's the 15th and I'm still bleeding. 10 days so far. It's not heavy bleeding like during my regular period but its kinda like the ending of a period when it's really light but it's a light pink and every once in a while kinda red. This period was more heavy than normal too. What's going on? Should I go to the doctor or is this normal?
