Tmi warning.

Please no bashing I never had this before. I'm 19 and I have pretty normal cycles. This last one lasted maybe four days. Normally they last about six to seven days. I've been off it since last week but earlier I wiped and expirerenced a streak of blood in my discharge? I am due to be ovulating.. Could it be related? It was a tiny streak hair line in it.
