Peak Day, Cervical Fluid and Conception, and Stress...

Hello Kindara!

I have 3 random questions ;)

1. Is Peak Day considered only to be the day of highest fertile cervical fluid? I’ve read elsewhere that it is also considered to be the day before ovulation. However, what if the most fertile cervical fluid is noticed several days before a sustained temp. rise (ovulation) and not the day prior?

2. Is noticing fertile cervical fluid (egg whitey/watery/slippery) necessary for conception?

3. How does the increase in stress and anxiety actually lower chances for conception (if it indeed does)?

Thanks so much and apologies if these questions have already been addressed elsewhere on the site!-PD31

Hi PD!

These are all great questions and we are happy to answer them!

Let’s get started. A peak day is technically defined as the last day of fertile cervical fluid before a change back to less fertile cervical fluid. It often, but not always, corresponds with ovulation day. Because ovulation can only be confirmed by a blood/urine test and temperature, the peak day functions as an estimation of when ovulation happens. Using the peak day to gauge ovulation is usually, but of course not always, effective. Some women notice the most fertile cervical fluid (their peak day) several days before a sustained temperature, but fertile cervical fluid allows sperm to live in a woman’s body for 3 days, at times even 5, so it’s still possible for them to get pregnant.

To address your second question, fertile cervical fluid is not necessary for conception, although it makes it a lot easier. While it’s possible for sperm to live in less fertile cervical fluid, it is not optimal for getting pregnant. Some women don’t experience the very fertile qualities of egg white or watery cervical fluid. However, if you experience any type of cervical fluid and ovulate within a few days, it is possible to conceive. Tracking your cycle will help you understand your personal cervical fluid pattern so you can correlate it with your temperature rise.

Finally, stress can absolutely lower your chances of getting pregnant. In one study, stress was found to significantly reduce the probability of conception each day during the fertile window through its negative effect on the sympathetic medullary pathway. Evidence also suggests that women who experience high levels of stressovulate on average 20% less frequently than women with low levels of stress, therefore decreasing the number of opportunities to conceive. So women who are trying to conceive should take measures, like exercise ormeditation, to decrease or keep stress at a moderate to low level.

We hope this information was helpful to you. Thank you for all your great questions and if you have any more, feel free to write in again!
