I had my period around 2 weeks ago, and then after I started spotting which happens and everything was normal. Then I started getting this dark almost black gunk, discharge. Sometimes it's either really light brown, red, or black. I have no idea why this is happening, cause it NEVER happens like this. I understand the body is cleaning itself out, but does it really take like 2 weeks?

If this information should help, I'm having symptoms like I'm on my period, moodyness, eating a lot, sore breast.
My normal period last around 7-8 days, so If I got it on a friday, it would end on a friday or possible saturday.

I'm just worried :-(
and I don't want to go to a doctor...
