Early, and it's brown/red why ??

Period ...is way early like I only got positive opks 6 days ago. I normally get positives on day 14 my cycles tend to last until at least 30 days sometimes 32.

Day 20, and my period shows up, she's not heavy but very brown ..no cramps. Tried taking a pic but the pic makes it look really red when infact it looks really dirty brown. is this normal or do I possibly have an infection or something?
