Ovulation Predictor Kits: Urine continued...

The instructions will tell you when to start checking your urine based on the length of your menstrual cycle. Then you'll test for 5 to 7 days. Some kits allow you to test more days.

Cost: About $17 and up

Ovulation Test Strips

These are the simplest and least expensive option. You hold the strip in your urine stream (or in a sterile cup you've filled with urine). Color coding will tell you if you're ovulating.

Cost: $13-$30

Digital Ovulation Tests include a digital readout, which can make it easier to see your results.

  • Digital Ovulation Test
    • Costs about $30-$50
    • Detects LH
  • Advanced Digital Ovulation Test
    • Costs about $38 for a 1-month supply and $54 for a 2-month supply.
    • Detects both LH and estrogen to predict your top 2 fertile days, plus another 4 days when you could become pregnant.

Fertility Monitor. This device stores the information from your monthly urine tests.

  • Detects both LH and estrogen. Some look for levels of another hormone, follicle-stimulating hormone (FSH).
  • Shows you low, high, and peak fertility days, adding another 1 to 5 days of fertility.
  • Stores information about your hormone cycles, so it tells you when to test and when your period is due.
  • Monitor costs about $160; the test sticks you need for the monitor cost about $50 for a pack of 30.

Ovulation Predictor Kits: Saliva

This type of kit looks at the mineral content in your saliva when it dries.

It comes with a mini microscope you can use to look for a pattern in your saliva that looks like a fern leaf. This pattern means you’ll ovulate sometime in the next few days.

  • Unlike urine kits, which you use only once, you can use a saliva test over and over.
  • A good option for women who want something simpler than a urine test
  • Cost: about $30
  • There are some problems with saliva testing:
    • Not all women will show the fern pattern or can see it.
    • You may not "fern" on all of your fertile days.

While saliva testing works for some women, it’s not as good as urine kits. "Of all the options, the only OPKs that have been validated are urine ovulation predictor kits," Schoolcraft says.
