Bleeding after ovulation, is this common?

Melissa
Ever since my dh and I have been ttc last July, I begin bleeding lightly two days after ovulation. I ovulated Sunday and two days later (today) I'm bleeding a rose colored, creamy blood. AF isn't due until the 15th. This only happens the months we ttc, other than this my period is regular. Anyone know what's going on? This is way to early for implantation bleeding.
