I have been using these this cycle and am on CD 14. Based off of the previous two cycles I should O btwn CD 15-18 but I just realized that I started using these on CD 7 as opposed to the CD 5 it says you must start using the sticks on. That seems pretty early to me and my DH thinks it's just to get you to use all all the sticks faster but I wanted to check with others. I will BD it EOD this week just to be safe
Re: Newbie -- Have you used First response digital opk?
I personally started using OPKs on CD 7 too,
There was another post on the board this morning and most women said they started OPKS on CD 10 ...
So don't worry
