I have only been temping and my temps are funny. Last night I had what seemed like ew cm with a medim height cervix and medium consistency. So I got curious and took an OPK mind you at 11pm and guess what? low and behold bam! POSITIVE! Now I am going because I don't know if I should just disregard the OPK's and continue by just temps which would have me at DPO4 or leave the + OPK which took away my O date. What do you think? I already know for a fact I am not DPO4 I was thinking more of a DPO3 or 2?

 I looked at your chart and I don't think that you have oed yet. I would go with the opk and expect to o today tomorrow or the day after. Good Luck. 

okay....   as much as it hurts because I thought I had gotten a O + 12 in there due to the high cervix and ew cm before. Thanks Brook 

only time will tell you which day is your real o day.
