Are you having trouble finding your luteinizing hormone (LH) surge or with your ovulation detection?....Is your ovulation chart looking a little different than everyone else’s?...Unsure if you ovulated or had an  LH surge? 


We are all unique; with different lifestyles, sleep habits and menstrual cycles. And just like most things in our life, ovulation tracking is not one size fits all. Altering your period and ovulation tracker method to fit your specific needs can help you to meet your goals.

Let’s Start With The Basics.

When trying to conceive, the first step is to find the right method to track ovulation. Everyone wants accuracy, simplicity, and convenience, but is it possible? Yes. 

First, have a clear idea of how the four natural body signals relate to one another. 

  1. A normal ovulation cycle begins with the first day of your period. 
  2. LH levels will then peak 24-36 hours before ovulation day. 
  3. Usually 24-48 hours after ovulation day, your basal body temperature spikes then progesterone levels continue to rise.

What Are My Tracking Options?

Ovulation testing, or LH testing, is the most popular method. Mainly, because it's simple and quick. Using LH tests will help you to predict when ovulation will occur by identifying the LH surge. 

BBT also has a large, loyal customer group, such as women who practice natural family planning. BBT helps to confirm that ovulation did occur. A great advantage of the basal body temperature thermometer is that it's a one time investment. 

Progesterone testing (PdG) is a new method of ovulation confirmation, it tests urine for metabolites of progesterone produced from ovulation.. 

The period calendar is the oldest method, first used when other tools were not available, and also cost effective. However, it only works when your period and ovulation cycle are both regular.


How Do I Know What Is Best For Me?

When choosing your method, know that each option has its benefits and challenges under specific situations. If you have the knowledge to deal with those challenges, you will still enjoy using your preferred method with hopes of achieving your goal of pregnancy. 

Please know:  One of the biggest challenges to women using ovulation tests is missing the LH surge. Here are solutions for different causes of missing the surge. 

Reason One:
Your LH surge level is too low to be detected, but you did ovulate.

The Solution:
Use the BBT chart or a PdG test to confirm that your LH peak resulted in ovulation. Find the darkest LH test line, even if it is lighter than the control line.

Reason Two:
Your LH surge is too short and has been missed.

The Solution:
Test twice a day between 10am and 8pm, three to five days before the predicted ovulation day until you catch the peak test line.

Reason Three:
Your LH surge pattern is not as normal or balanced.

The Solution:
Choose a second ovulation tracking method such as BBT or PdG when LH is imbalanced

If there is no perfect single method for you, then combining multiple methods is probably the best choice. A combination of using ovulation tests, tracking BBT and PdG testing will help you to better predict, plan and confirm your ovulation.
