Your Quick Guide to Ovulation Predictor Methods

 What are the different methods out there for ovulation prediction?  Since there are several methods out there to try and predict your most fertile window, it may get confusing trying to figure out which is the best method for you. Below are the the Pros and Cons to the most common types.  

 

Ovulation Predictor Kit: Urine Luteinizing Hormone (LH)

There is a hormone in your body called the luteinising hormone (LH) that rises one to two days before you ovulate. To use OPKs using urine, you urinate on a LH test stick that notifies you whether or not there is a surge in the hormone or not.

Cons:

  • Inconvenient: you must ‘pee on a stick’ one or 2 times per da
  • A high percentage of women do not produce enough LH to trigger the test to show positive
  • Not consistent in women over 40 years old Does not test if ovulation occurred
  • Need to chart in order to test on correct days
  • Confusing at times to know when to do the tests
  • Color changes are often difficult to interpret

Pros:

  • Widely available
  • Easy to Use

 

 

 

 

 

 

 

Ovulation Predictor Kit: Salivary Ferning Kits

When it’s near your time to ovulate, your estrogen levels increase. These tests are observed under a small portable microscope. When it’s time, your dried salvia may form a fern shaped pattern.

 

Pros:

  • Somewhat easy to use
  • Non-invasive

 

 

 

 

Cons:

  • Not all women fern
  • Sometimes difficult to see and/or interpert results
  • Women who fern on some days of their fertile period, don't necessarily fern on all of their fertile days
  • Ferning may be disrupted by eating, drinking, brushing your teeth or even how you put your saliva on the slide.

 

Basal Body Temperature:  This method is used by taking your temperature daily to detect a rise in your basal body temperature (your temperature when you are fully at rest). The rise in temperature indicates that you have ovulated.

Cons:

  • Is not truly predictive of ovulation - BBT tells you when you just ovulated, and not the days BEFORE ovulation when pregnancy is most likely
  • Inconvenient: waking up at 6am every morning, even if it’s the weekend, and possibly waking your partner each day, is a nuisance.
  • May take several months of tracking to pinpoint fertile window  
  • Can be skewed by outside interferences such as lack of sleep, a glass of wine, and medications 
  • Changes in temperature may be difficult to interpret

Pros:

  • Affordable
  • Detects if ovulating

 

 

 

 

 

 

 

 

 

 

 

Priya Ring:

There is a very subtle dip in your temperature right before you ovulate. This is the time to get frisky! Since sperm lives for 2-5 days, if you have intercourse during this time, your body will work like a catcher’s mitt waiting for the egg and significantly increase your chance of getting pregnant.  The Priya Ring is a vaginal fertility sensor (the most accurate way to catch that subtle dip) that monitors your temperature and sends a message to your smart phone when you are most fertile. 

Cons:

  • May be pricy for some
  • Must have internet access
  • Need to be comfortable with inserting ring into vagina

Pros:

  • Effortless: simply insert and Priya does the work for you
  • Accurate: since it is inside your body, no room for human error
  • Discreet: No one knows you are wearing it! 
  • Can tell you if you have ovulated the first month of use
  • Comfortable (can’t feel it)

 

So which one should you use? Since there are a lot of things to consider, including whether or not your period cycle is regular and any medications you may take, you may want to consult with your doctor to see which one will work best for you.
