ovulation spotting?

I'm an supposed to be ovulating this week, my husband and I have been having sex at least every other day. Yesterday was supposed to be my best day so last night we had sex, this morning when I got up and went to pee I had some light spotting when I wiped, any ideas what that is or could be from? 
UPDATE: it's now brighter red and more like period bleeding but I'm not due till the 27th...
