Enter Your Fertility Signs Daily

    Your primary fertility signs are:
  • Basal Body Temperature (BBT)
  • Cervical Fluid

Basal Body Temperature

Your BBT is a fertility sign that will help you pinpoint your ovulation day.

It's recommended that you take your temperature every morning before you get out of bed. For the best results, aim to do this at the same time every day.

  • Your BBT is your waking temperature recorded with a BBT thermometer.
  • Take your BBT BEFORE getting out of bed.
  • Your BBT rises after ovulation. The rise can be about 0.4°F (0.2°C) but may be smaller or greater.
  • BBT or accurate digital thermometers are available at most pharmacies and drugstores.
  • Tips for accurately taking your BBT

Cervical Fluid

  • is the fluid produced by the crypts of your cervix
  • can also be called Cervical Mucus (CM)
  • can change throughout your menstrual cycle depending on your fertility status
  • can be found on toilet tissue when you go to the bathroom
  • it can be slippery and like raw egg-whites when you are the most fertile

Recording your Cervical Fluid Data

  • Record the cervical fluid type that best fits your observations.
      A typical cervical fluid pattern can be:
    • Dry or sticky after Menses
    • Creamier (lotion-like) as ovulation starts to approach
    • Slippery and stretchy like egg-whites during your most fertile days before ovulation
    • Can dry up after ovulation.

Most Fertile Days

    A female is fertile for just a few days each cycle. To increase your chances of conception, you need to have intercourse during those days:
  • You are most fertile on the days just before and up to ovulation.
  • You can only conceive during this phase of your cycle.
  • You will see that your FertilityTies.com Ovulation Calendar displays a "Green Light" on your estimated fertile days.

Ovulation Patterns

  • Your BBT will rise after ovulation.
  • Ovulation usually occurs the day before your temperature rises.
  • Once you have a sustained rise (3 days or more) the FertilityTies.com Ovulation Calendar will mark your ovulation date on the chart.
  • Please note that if you're taking fertility meds you could be ovulating later during your cycle. Consult with your Doctor if you don't ovulate while taking meds.
  • Tips for successfully identifying your ovulation date

What Happens After Ovulation

  • Remember this phase of your cycle is called the Luteal Phase.
  • Your temperatures are likely to stay elevated and your cervical fluid returns to a dry state.
  • The luteal phase can vary from 10 to 16 days from woman to woman.
  • The luteal phase is usually constant from cycle to cycle for the same woman.
  • If you are pregnant your BBT will stay elevated beyond your usual luteal phase length.
  • If you do not become pregnant your BBT will usually drop at the end of your luteal phase as you get your period and begin a new cycle. Good luck next cycle!

Reading Your Chart


Your chart is a summary of your cycle. Dr. Quintero a Reproductive Endocrinologist and a medical expert for FertilityTies.com has put together an explanation of each phase of your cycle in an effort to help all women out there understand their reproductive systems better. You can read his version here.


    Cycle Phases

    Your cycle is composed of the following phases:
  • Menses : This is your menstrual period. Your cycle begins on the first day of your full flow period. Also known as CD1. Read more about menses...
  • Follicular Phase : During this phase your eggs mature and your body prepares itself for ovulation. You are the most fertile towards the end of this phase. The dominant hormone during this time is estrogen. Read more about the follicular phase...
  • Luteal Phase : This is the length of time between ovulation and your next period. It usually lasts around 14 days. If conception occurs, implantation of a fertilized egg happens about 7 to 10 days into this phase. If there is no conception, the lining of your uterus is shed (your period occurs) and your body prepares for a brand new cycle. The dominant hormone during this phase is progesterone. Read more about the luteal phase...
  • Fertile Phase / Best Time To Conceive : You are the most fertile during those days preceding ovulation and the day of ovulation. The main advantage of charting your fertility is helping you identifying these days to increase your chances of conception. Read more about the fertile phase...
