In addition to the evaluation, trackle also shows you prognoses. These prognoses are provided from the second trackle cycle onwards. The prognoses will become more precise the longer you use trackle and will help you to know beforehand when you will probably be fertile and when you won’t. 

However, prognoses are not 100% certain predictions of your cycle, but they are really only that: prognoses!

In theory (meaning with a completely regular cycle of 28 days), ovulation statistically occurs on day 14 of the cycle. In reality, however, this calculation works for less than 20% of women. The time of ovulation can change in every cycle. Our hormones react to our personal circumstances. After all, the ovum grows in order to potentially be fertilised and your body pays close attention to the circumstances for that: stress, illness, psychological issues, travel, etc. can all cause the time of ovulation to shift and the length of the cycle to vary.
