Choosing The Right Ovulation Predictor

Wanting to have a baby and waiting for that right time to conceive? Nowadays, there are a number of ways to check your ovulation. An easy and quick way is using an ovulation predictor kit (OPK), which you can choose from two kinds, the urine-based OPK and saliva-based OPK. For the urine-based OPK, it will identify the luteinising hormone (LH) surge that is produced a day or so prior to ovulation. As for the saliva-based OPK, it tests for rising estrogen levels when you’re near ovulation. Both can usually be bought from a drugstore or even online.

Urine-based Ovulation Predictor

To let you know more about the urine-based ovulation predictor, here are some of its pros and cons:

  • convenient (for it can be bought from drugstores or online)
  • mess-free (simple to use by just dropping a sample of your urine)
  • needed to be used only in your mid-cycle not on everyday basis
  • proven to be more accurate compared to charting cervical mucus and basal body temperature
  • more recommended for women whose temperature don’t rise after ovulating
  • it can predict ovulation even just six hours before happening, so you know when to have intercourse


  • it can be expensive, price of sticks as a set may vary
  • it can test for the luteinising hormone (LH) surge that is produced right before your ovulation but it is in no way a confirmation that you’ve actually ovulated
  • you should strictly follow the directions to get accurate results
  • most fertility drugs can invalidate results
  • it’s not recommended for women with irregular menstrual cycles, in using this they should do more than the 5 to 9 predictor sticks for testing daily that’s included in ovulation predictor kits(OPK)
  • it can’t indicate the incidence of the cervical mucus, which is egg-white in texture which should be present to conceive successfully

One popular and highly rated Urine-based Ovulation predictor is Clearblue fertility Monitor.

Saliva-based ovulation predictor

For the saliva-based ovulation predictor, here are some of its pros and cons:

  • lightweight and pocket-sized
  • portable to bring with you anywhere
  • inexpensive, after buying the ferning microscope, no additional materials needed
  • not for everyday use, only in your mid-cycle
  • it can predict ovulation 3-4 days before happening
  • convenient and mess-free


  • it can be difficult to see the ferning patterns for those with poor eyesight
  • after two years of use, you should buy a replacement
  • fertility drugs can invalidate results
  • can’t indicate the cervical mucus
