Bleeding on fertile week?

Lou Boo

AF ended 5 days ago. I’m getting high clear blue readings the past 2 days and I’m in day 2 in to the fertile week.

Due to ovulate on Tuesday 26th March.

BD last night and very noticeable red blood on my partner. I was shocked as 5 days later. If older flow it would be darker I felt?

I’ve never had this before? Any advice?
