Fertility Friend has been switching around my o date and I'd like to pin it down so I know if I am testing at 8 dpo or 10. 
Here is a link to my chart. If I remove all of the opks, it gives me a dashed line saying I likely o'd on cd 20. If I put them all in like they are now, it says cd 21. If I take out the opks on cd 21 and 22, it puts my o date at cd 20.
Here is a link to a pic of my opks. I figured since cd 21 and 22 were darker positive than cd 20 I would put them as positive on my chart. Is that wrong? Should I just stop testing once I get a positive?
If I really did o on cd 20, wouldn't I have gotten a positive opk on cd 19 or 18? Has anyone ever had a positive opk the DAY they ovulate? Is that normal? I thought it was about 36 hours in advance. Sorry for all the questions, I am a charting newbie.
Thanks in advance for any help you might have to offer. You ladies truly make this ttc process a whole lot easier!
