What day of your cycle do you usually start testing? I know everyone's bodies are different, but I'm curious as to what others do. TIA!

Re: Question for OPK users...
Usually if you are new to using OPKs, start testing on CD 10, and once you have a couple of cycles under your belt, go from there.
I can usually always predicate for myself from CD 12-14, with a CD15 thrown in there every once in awhile.
I start checking CD7 or CD8.. So, I only skip one day after the end of AF. No, I don't expect to see a positive that soon... but.. it gets me in the habit.
July - Nov 2011: Testing with OB... OB said everything looks good
March - Sept 2012: Moved to RE.. 4 treatment cycles - responses of one or no follicles
09.03.12: Diagnosed Poor Ovarian Response.. DE IVF only option
Feb - Nov 2012: Pursued Adoption. That door slammed shut.
12.23.12: Surprise BFP (first ever)... 12.25 - 12.31: Natural M/C
This is my first cycle and I started CD 8 or CF 9 ...
I was only testing once per day until last week, when I started testing twice ...
Good luck
My Dr. told me to use them between day 10-17(if you are using the 7 day kind) and you are most likely to hit your surge (I know not true for everyone). This last cycle I used them starting day 11 and got + on day 15 & 16. If I had started using them when the instructions on the package said, I would have missed my surge altogether.
GL!
