  • like, how do you use them???
    They help pinpoint ovulation... several days before you expect to ovulate you pee on the stick like a pregnancy test... you typically would have 2 lines, but 2 lines do NOT mean a positive (like with a pregnancy test) the test is only considered positive when the line is as dark or darker than the control line... which means you will ovulate within the next 24 hours usually. If you have irregular cycles they can be very helpful... but they aren't that helpful if you ovulate the same time each month.

  • They detect luteinizing hormone (LH) in your urine, which peaks 1-2 days before ovulation occurs. LH is continually present in your urine, though, so instead of the 2-line positive like with pregnancy tests, an OPK is only positive if the test line is as dark as or darker than the control line. When you get a positive, it means your body is preparing to ovulate, and thus that you are in your most fertile time period, during which you have the best chance of conceiving.
