Mid cycle bleeding

Paige • Pregnant with baby #2 🌈
Has anyone ever had mid cycle bleeding? I am on cycle day 15 (of a 29 day cycle) and I have had red spotting for three days now. I've never had any bleeding outside of my normal AF before. This is my fertile window but I am not sure if I should be trying right now or not!
