Ovulation spotting?

My predicted ovulation was yesterday. I’ve had unprotected sex almost every other day (if not more) since my period ended. Today I’ve had very little light spotting. First time it was pinkish/bright red. The second time it was more brownish and then it was gone. Have any of yall experienced this and if so could this be a sign of early pregnancy? I miscarried in September and had to get on birth control to regulate my cycles and this is the second month ttc ❤️
