So confused..

I belong to this site and ovusoft..ovusoft says I ovulated on the 20th..leaving me at 11dpo..glow says I ovulated on the 19th and says period is due tomorrow..yesterday whilst checking my cervix position I wiped my finger on to and it was yellish, pinkish...now today nothing..I want to get excited that it's possibly IB and not AF cause I have felt completely off this go round..guess I'm just venting..
