This month I am going to start using OPK’s and while in the local drug store I noticed that 20 OPK’s is a “month supply.” I was actually a little surprised, I didn’t realize you would use so many.
I am on CD6 and AF is on her last legs so to speak. My ap that tracks my cycle estimates OD as October 17th. Just trying to figure out when to start testing to be sure.
Help me out ladies. When do you start using the OPK’s? How often (daily, multiple times a day)? For how long (days)?

It depends on the length of your cycle. But most will start around CD 10. Test 2x a day so you don’t miss your LH surge. Usually later morning and evening time. Not first morning urine like a HPT. Remember that you want the test long the same or darker than the control line. You always have a little LH in your system, so don’t be surprised if you see a faint line. Once you get a positive, you should ovulate 24-48 hours later so get to BDing. 🙂 hope this helps. I thought I O’d close to CD 14. But opks showed me I am closer to CD17-19.

Good question, see below for what technique I use.

@Treejewel19: Yes, you can end up using tons of OPKs. I am late O-er around CD19-22. What I started doing to save some sticks is wait until EWCM starts to show up, either that or I start testing around CD14 once a day between 12-8 pm. I noticed my OPKs get progressively darker the closer I get to my actual O day. Once I see them getting close to positive, I test twice a day once around noon and one later in the evening. I usually get two days of positive OPKs, so I am not too worried about missing the surge. Then I confirm with elevated basal body temps. Good luck!

@Treejewel19: I start using them around CD 10, and test in the afternoon (around 1:30pm, or 4:30pm, depending on my work schedule!) every day, once a day. Last time I got a positive 48hours before ovulation! Hope that helps.

@Treejewel19: I was a true first-timer with OPKs this month too! I typically ovulate closer to CD18-CD20 but last month I started testing at CD14 just to see and got a positive! This month I started checking on CD12 and got a positive on CD15 and CD16. I’d say start 5 days prior to your typical O day, but some folks start immediately after their period is over just to be as careful as possible so as not to miss the surge.
It helped me to read up on the LH surge and when it happens — typically overnight or early morning — and it may not be detectable until mid day or early afternoon. I found this article really helpful: http://coloradofertility.com/patient-resources/the-lh-surge/
I’ve been stuck in a Catch-22 between drinking lots of water for good CM, and then my urine being really diluted and tests hard to read! I just saw on FertilityFriend.com that they recommend limiting fluids and doing a 3 to 4 hour hold of your urine for best results. I got my two positives later at night after working out (random, right?) and having a 4-6 hour hold.
Best of luck!

I started testing at CD8 my first time using OPK’s and I’m glad I did because I apparently O pretty early: CD11 or CD12 (I have 2 days of + OPK’s with the first + on CD10 or CD11). I have a 27 day cycle. If you have a 28 day or less cycle I’d suggest starting a little earlier than CD10, maybe CD8, just in case. It’d be worth it if you do O early. Had I missed it I would have thought I was just doing it wrong or the OPK’s didn’t work. If your cycle is longer then I think starting to test on CD10 would be fine. I typically test once a day (second morning urine, 10 a.m.-ish) from CD6 then twice a day (10 a.m.-ish and 8 a.m.-ish) after I get fertile mucus. Once you know when you O you can restrict it more to save money on the tests, but I I’d personally rather spend a little more the first month and know rather than chance missing it.
