A fertility chart pregnant example is a graphical representation of a woman’s menstrual cycle, used to track her fertility and identify the best time to conceive. It involves recording daily observations such as basal body temperature, cervical mucus, and other fertility signs to identify the fertile window.
Fertility charts have been used for centuries and have proven helpful in family planning, infertility diagnosis, and improving pregnancy chances. A key development in the field was the invention of the basal body thermometer in the 1950s, which made it easier to track temperature changes related to ovulation.
