Peach color discharge

Okay so Friday was my last full day of my period when i thought it was going to last until Saturday or Sunday.. well i have had sex everyday since then and today when i went to the bathroom and wiped there was a small amount of peach color discharge on the toilet paper. There was not any on my panties just that small amount on the toilet paper. It wasnt thick it was more like liquid if that makes any sence and very light in color, anyone have any idea of what this could be?
