How Lady-Comp works
Every woman has a unique menstrual cycle
The menstrual cycle varies individually from woman to woman. The menstrual cycle begins with the first day of bleeding, which is counted as day 1. The cycle ends just before the next menstrual period. A typical cycle is assumed to be 28 days, but some women may have shorter (25 days) or longer (36 days) cycles. The computer will use this personal cycle pattern as a basis for its calculations. With time, if the user has regularly entered her daily temperature and menstruations, the computer will know that this user will likely ovulate on day X of the cycle and her monthly period will start after X days.
The 3 phases of the menstrual cycle
- The infertile phase at the beginning of each cycle, including menstruation
- The fertile phase around ovulation
- And the infertile phase after ovulation until the next menstruation, called the luteal phase
Hormones and Temperature
The above graphic illustrates the individual processes of the female monthly cycle and shows how they are reflected in the temperature curve. For this example, we use an average 28 day cycle where ovulation takes place on the 14th day. Please be aware that this is a statistical example, most women have cycles that vary by a few days and ovulation varies from cycle to cycle.
During your monthly menstrual cycle, two hormones race through your system. During the first half of your cycle (menstruation and the follicular phase - from the first day of menstruation until ovulation), estrogen is the dominant hormone. Estrogen helps your ovaries produce an egg that is released during ovulation. During the second half of your cycle (the luteal phase – from ovulation until menstruation begins), progesterone takes over. After ovulation, the increase in progesterone production causes a slight, but easily detectable increase in your basal body temperature. Progesterone will dominate until it falls in anticipation of your menstrual period.
The intelligent fertility tracker with a accuracy of 99.3% shows you exactly when you are fertile and when not.
This is the pattern on which the computer bases its calculations to specifically filter out the days of a cycle when intercourse could lead to pregnancy. In this fertile window, you are free to choose whether you abstain from sex, use a barrier method of contraception, or plan for a baby.
Irregular menstrual cycles
Cycle irregularities are common; not every woman has a regular cycle. There are many factors that can alter the regularity of the menstrual cycle, including illness, travel, hormonal imbalances, stress, extended partying, sleeplessness, dietary factors, and more. The computer will predict the course of the cycle based upon the user’s unique cycle history, but current fertility indicators are based upon the temperature readings that have been entered for the current cycle.
These calculations are made for each individual woman and comprise the typical highs and lows of the temperature curve before and after ovulation. Lady-Comp analyzes each temperature reading for accuracy. If it detects an occasional outlier, it will be ignored and will not influence the calculations of your daily fertility diagnosis.
Menstrual cycle influencing factors
The female cycle can be thrown out of balance. This can be observed particularly in situations of physical and emotional stress. For many women, situations such as an exam, moving or even a vacation can delay or even completely suppress ovulation and/or menstruation.
