How accurate are OPKs?


I'm visiting from the LTTTC forum for a bit of advice from you lovely ladies who are a bit more in the know about OPK testing. I never used them because I was so irregular and not ovulating so it was very depressing. I decided to give one a go this month and got what I thought was a positive on day 15. Both lines were the same colour but in the past I always had one blank and one with a line so knew they were negative. Its now day 29 and no yet. After over 2 years TTC I don't want jinx things by testing but I wanted some advice:
If I did get a positive OPK on day 15 did I ovulate on day 15 or day 16?
If so, does that mean AF is due on day 29 or 30?

Please be brutally honest with me as don't want to get my hopes up!

Thank you.

I think that when you get the positive line (which by the sounds of it you definitely did!) then it's the day after.

When did you bd????

Hi!

Well I have a limited knowledge of opks (only started using them myself this month) But from what i understand if the test line is as dark or darker than the control then its a pos. You normally ov 12-36 hours after a pos opk, and i think it depends how long your lp is as to when you will get your period. I hope that helps a little xx

Hi ya, if you got a positive on day 15 you are likely to have ovulated 12 to 48 hours later, depending on the sensitivity of the kit and whether it picked up the lutinising hormone at the start or beginning of the peak. And mini surges can happen too, I have read. So you probably ovulated on day 16.. The second phase of your period after ov varies between people, but is usually quite constant for the same person. So it may be something you will need to work out over time. For example, mine is 12 to 14 days long, so if I ovulate early on day 12 I would get a short cycle. Good luck.

Hi, with my limited knowledge, but experience of four months using OPKs, research suggests that you ovulate between 24 and 36 hours after your positive OPK, although some sites say as little as 12 hours. FF (fertility friend) can also site ovulation on the same day. Maybe you should temps well as this is a cheaper and easier way to "see" your progress. I do have to warn you though even positive OPKs doesn't mean you have definitely ovulated (only slim chance you haven't though) so it's only a guidance. If you picked up a second line of the same colour then that is a positive surge. I hope you bded lots over that time. To really catch that egg you need to bd before rather than after ovulation. Hence why OPKs are good as they give you warning.

Good luck and let us know if you caught it! I'd wait until your AF is due before you test. That is what we are going this month. xxxx

THank you all for the quick responses! I'll hang on for another couple of days before I test. Trying not to get too excited...
