Bloody cm?

Not sure exactly where I am in my cycle. But I did have a period like 12 days ago. (Idk if I’ll ovulate or already did?) I had a baby not quite ten months ago and I feel like my body isn’t “back to normal”. I had trouble conceiving her so I don’t think I can get pregnant on my own (without medical intervention). Anyways... Anyone know why I’d have bloody cm today? Of course yesterday was Valentine’s Day and hubby and I dtd but we do that often and I never bleed. I’ve had more cm than usual today also.

*We are not TTC right now but not preventing it either.
