Spotting at 3 DPO.

Salena
I ovulated on Monday and on Wednesday started spotting. It's a bright pink, but very light blood. I also had some spotting yesterday and again today. I know it isn't my period because it is always EXTREMELY heavy, plus I'm regular and not due to start for another week and a half. Could it be from ovulation? My opk was positive Sunday and Monday. Picture is of Monday's opk.
