ajillity81:  You can techincally O 12-72 hours after the first + OPK. 24-48 is most common. I O pretty quickly after my positive OPK, less than 24 hours after (I can see this from charting the past 6 months). I have short cycles too (25-27 days) and a longer luteal phase (15-16 days). I am an early ovulator, I usually O CD10-12 myself, most often CD11. I begin testing CD8, twice daily (late morning and before bed).

You may be able to test once daily, but it depends on how short or long your LH surge (which is what the OPK detects) is. I see two days of positive OPK’s, so I could test once daily but choose not to. Some women only see one day of positives and some women have a LH surge that is so short they may miss it if they only test once a day. I would suggest testing twice daily until you figure out what your LH surge is like, then switching to once daily later if you are comfortable doing so.

Personally, my ‘true’ positives have a test line that is darker than the control line. A line equal to the control is positive, but I don’t count it unless it is darker becuase for me, this is the peak of my surge, not when they are equal. I can also see a gradiation as my tests lines get darker, which helps me plan BD, though some women cannot. I would BD every other day from around 3-4 days before you O until O is confirmed. My DH is like yours and this works well for us. If you don’t know when you O yet I’d BD the day of the OPK and the day after until you figure it out.

I hope this helps:) If you have any more questions you can lask away

ajillity81:  If you have never used OPKs, I would recommend testing twice a day. You may have a very short surge and if you test once a day, you may miss it. The last 3 cycles I started ovulating earlier (CD11/12, confirmed by temperatures) and if I had started testing at CD10 I would have missed my surge. I usually have a positive OPK and it goes back to negative after a couple of hours, so unless I test twice a day, I would miss my surge. Best of luck!

My surge was pretty sure so I’d test 2-3 times a day. If I didn’t, I was really likely to miss it, and I still did miss it a few months. Also, I wouldn’t wait to BD at all. Heck, I suggest starting to BD at the first sign of fertile CM. Because if you wait until you are Oing or O+1 you’re basically too late. It’s possible on those days, but unlikely. The reason that FF includes O+1 in their estimator is to factor in the possibility of an overnight O. Still, you really want the swimmers already hanging out when you O. 

Good luck!

The LH surge doesn’t start until late morning, so I might suggest the 10’s. You might miss it at 9 a.m.
