CD16 Advice

Hey everyone! Need some advice and input on this situation. On CD16 me and my BD’d and right after I noticed some light pink spotting (sorry for the TMI). I know it’s not implantation bleeding since I don’t usually ovulate until around now, could this be ovulation bleeding? I’ve never had this before, so not sure what’s going on. If it is ovulation bleeding, and because we BD’d, could this increase my chances of getting pregnant, or does it not really make a difference?
