How Much Does Your O Date Change?

How much does your O date change from month to month?

For ex: does it change by like 2-3 days or more like 5 days or so? I O'd last month on CD 21 and Im wondering if I should assume that it wont be exactly CD 21, but that it'll be off 2-3 days or so?

I usually "O" between CD22 and CD24 so it really only changes by about 2 or so days each month.

The past two months i have Oed on CD 18 & CD 19. This months based on my temps I think it is going to be more like CD 16 or 17. So for me it only ranges like 2 days or so.

I'm like this too. I started checking O since last year and I have seen + from CD26 to more recently, on CD13-14. Now, I dont know if that has anything to do with the fact that I had a hysteroscopy, recently (9/30) and my RE removed some adhesions. Who knows?

Re: How Much Does Your O Date Change?

The first month I O'd since being off BCP, I O'd on CD23. Last cycle, I think it was around CD22 and this month it was CD20. My guess is that I'm still finding my way after BCP.
I start using OPKs at CD 10 b/c I'm never sure if it's going to move up.
