morning girls, hope all is well

Getting confused here, as I am still waiting for OV. I usually have a 28/29 day cycle, so should have OV by now. The longest cycle that I can ever remeber having is 33 days, and going by that, i should be OV about now, but there is still nothing on my OPK's!! i will be very worried if OPK's are still showing nothing by sunday.
Also, i had 2 small red bleeds which has never happened before, (CD13 and 15) and I have been using OPK's since CD11. GGRRR, whats going on?!
