Spotting during ovulation

Been trying to get pregnant for a year- usually cycle is pretty predictable and yet not pregnant.

This cycle was weird..creamy discharge day before projected fertilization (usually I have no CM)and spotting (like a drop or 2 of brown discharge a day) for 3 days after the creamy discharge (usually don’t bleed/spot at all until day or so before period) then on 4th/ 5th day (projected ovulation day) I have watery CM.

All this is very different then all my other cycles..had sex only 2 days out of the fertilization days (maybe tonight too).

Anyone know what all that could mean?
