Bleeding mid cycle

So I had period 12/29 ended on 1/2 had inercourse 1/1 with husband who didn’t pull out(we are okay with it).

Yesterday I wiped and good amount of blood.Not brown but fresh and no clots.

But today when I wiped I saw this(picture) and rest of day my discharge was dusty rose/ brown color.Anyone have any idea?

It could be stress due to other health concerns I had day prior or meds I’m taking but just brain is working overtime 🤔
