Red day Facts

A common question we often get from new users is: “Why do I have so many red days? Am I always fertile?”

The answer is of course, no! No woman is fertile for more than 6 days per cycle. The fertile window starts 5 days before ovulation (because sperm survival is ~ 5days) and ends after ovulation.

Before NaturalCycles can pinpoint your 6 day fertile window it has to first get to know what is normal for you. After all, every women is unique.

So what else can influence your number of green days?

Quitting the pill

Women who quit the pill (or other hormonal contraceptives) and switch to NaturalCycles question the number of red days they get at the start. Why? This is because hormonal contraceptives disturb a woman’s normal menstrual cycle, thus leaving women with irregular cycles until the synthetic hormones leave their bodies, and this can take several months. NaturalCycles takes this into account, giving more red days until things start to get back to normal.

Measuring and fluctuations

Another important factor to consider is, how and when you measure your temperature. We advise you to avoid measuring when you are sick, feeling hangover or if you wake up much later/earlier than usual. You can read more about measuring and basal thermometer here

Your temperature varies from day to day, but more considerable fluctuations can occur during ill or hungover days. These fluctuations in temperature can resemble ovulation or otherwise, which means NaturalCycles will give you a red ‘fertile’ day just to be safe. If you think this has happened to you then please get in touch at support@naturalcycles.com and we can take a look at your data and remove the anomaly that might be tainting how your cycles look.

So with this in mind, please don’t loose hope as green days are just around the corner. The more data you enter, the better NaturalCycles can pinpoint your fertile window, giving you green days in return. Have a look at this happy cycle:

To find out your fertile window and ovulation day faster, we also recommend taking an LH-test. A surge in LH hormones occur two days before ovulation and marks your most fertile days. NaturalCycles let’s you know when to check your LH levels, which also depends on how regular your cycles are. Have a look below to see what our reminders look like:

So to sum-up – don’t worry, because green days are ahead! Just make sure you keep measuring everyday!
