My Dr. told me to test cd12-17, but I usually test to cd20 just to be safe.

I’ve heard to start testing on cycle day 8. I know what some people do is use the cheap OPK’s until they think they get a positive, then use the digital OPK to double check. That way it’s not as expensive.

I usually start around CD8-9. I get my positive OPKs on CD10-11. I usually stop after CD13 (projected ovulation for 27 day cycle).

I second QBbride. You should start on CD 8 unitl you get a positive. I always get the dollar store OPK’s, since the name brand one’s can get expensive, and they work just fine!

Since my RE wants me to start using OPK, I’m tracking CD 10 onward.  I have ovulation pains as well as track my EWCM so I don’t need to track a full seven days.

I started using them around day 10 and usually used them up for at least 5 days after my surge ended.  So, if I got a positive OPK on day 14/15 I would use them through day 20.  I had one flukie OPK that I got on CD11 and really was perplexed by it.  I kept testing and lo and behold got a real positive on CD 21 (confirmed ovulation because got period 12 days later!)

@roxy821: I have ridiculousy long and irregular cycles too, and for that reason, I start OPK-ing from the day after my period ends right through. It’s usually CD6 onwards. That way, at least I know I didn’t MISS a potential ovulation…

I have 31-32 day cycles so I don’t usually start testing until CD 12 at the earliest.  I usually get positive OPK’s around CD 16-17.

The first month I started testing, I started on CD 8 just to make sure I didn’t miss it.  I had a lot of negative OPK’s and the day that I was going to give up and not test was the day I got the + OPK.  Go figure.
