Your estimation of when you O from an OPK is always going to be a rough estimate – the only way to be exact about it is by charting BBT.  When you get a positive OPK, you will generally O within 12-48 hours.  If you want to not drive yourself crazy and test too early, I’d say to count the next day (CD19) as your O date, then wait until 11 or 12 DPO to test.  Since you’re at CD29 now, I’d say you could reasonably start testing tomorrow or Saturday.  Good luck!

The olulation kits work amazing. Thats how i had my first two kids and will use them when I try for my first with my new husband, were starting on honeymoon. I always got a strong positive day 11 so I would ovulate day 12 or 13.worked like a charm.So much easier then charting!

sara_tiara:  I’ve only done charting/temping because I bought an expensive OPK and ended up starting it too late (said no more then CD5 or else it may not read levels properly) and I ended up screwing it up lol. I just took my temp and plugged it into FF… recorded when we BD and thats it. I found that easy rather then guessing as I heard from other bee’s OPK’s can be hard to read/figure out when its actually positive rather then justa  “strong” read. Charting you get your temp spike and there you go lol. I guess the main thing with OPKs thats good is you get an indication of when its happening so you can go ok….I think I might be so we better BD for a few days.

I had a digital where it was just a “yes or no” and I think I would have liked the lines better. Im currently pg so I dont need it but if we were to go for another one I’d probably try the non digital opk just to see.

But as far as I know its hard to tell whether you did or didnt O for sure unless your temping :s

I really hope this is your month!! But if for some reason it’s not, I would highly suggest charting BBT in addition to OPK’s next cycle… then you’ll have a much better idea of when you O..  Good luck!
