Saw pink when I wiped but I already had my period this month, and I don’t ovulate for 4 days?

Katie • Baby #2 on the way 🥰💘

I never thought I would be one of these girls posting blood pictures, so I’m sorry. But I’m really confused. I’ve never spotted in between periods. My fiancé and I didn’t have rough sex whatsoever tonight, so what could this be?
