Cycles act in response to life and are therefore always of different lengths. This is very uncertain, if fertile and infertile days are determined by calculation and summation. No matter whether calendars, string of pearls or apps are used for this determination.
After waking up, first measure the temperature and enter or save the value in a chart. Pay attention to possible disturbances such as illness, difference in time of the day. The temperature rises around ovulation and the infertile time begins on the third day.
Sperm can survive in the mucus from uterine cervix. If you feel moisture or see mucus at the entrance of the vagina, you must assume fertility until the mucus is gone for three days. Make a note. There are potential disruptions such as bleeding, arousal, illness.
You can figure it out by palpating the vagina with a clean finger. The cervix is softer, open, higher and in the fertile period.
The cervix opening and mucus can also be checked with the help of speculum, mirror and lamp.
Body signs are combined and evaluated by way of dual check. This allows more women to very reliably determine infertile days. (Pearl Index 0, 4)
You always have access to aids in the market for observation and evaluation.
