Am I okay????

Elliana

I was on my second to last day of my period on the 17th...I had unprotected sex on the morning of the 18th and took a take action pill (the morning after pill) about 6 hours after sex.... my period ended on the 18th and stopped for 2 days... I had some brown discharge when I woke up today on the 21st and now I'm bleeding completely.... what's wrong with me???
