A normal menstruation lasts between 3 to 5 days.
The last day of a menstrual cycle is always the day before bleeding starts again.
Cycle lengths vary naturally during a woman's fertile life but tend to be more stable between 20 and 45.
That is why the day of ovulation may vary greatly, from cycle to cycle. Studies repeatedly confirm that ovulation on cycle day 14 or 15 happens only in one out of 4 cycles.
This is when experience and the knowledge from 30 years of charting makes all the difference. The Lady-Comp program compares your unique temperature pattern day to day with the data from over 100,000 menstrual cycles to detect your ovulation and your safe infertile days. Fast and easy.
So the next time your menstruation is late, you will know exactly if you are pregnant or if your ovulation was just a bit delayed.
I chose Lady-Comp after the birth of my daughter. For me, Lady-Comp is a reliable and reassuring method. Being able to get my cycles analysed by professionals really is a plus!
