Progesterone is one of the important hormones in the female body and plays a vital role in the female reproductive process. Let’s look at the three phases of progesterone: follicular phase, ovulatory phase, and luteal phase.

The follicular phase is the time when progesterone is highest and usually occurs several months before a woman becomes pregnant. The main purpose of this period is to allow the original eggs in the ovary to mature and form vesicles for the future formation of a fetus. During this period, a woman's body will undergo a series of changes, including increased body temperature, increased blood HCG levels, increased appetite, and enhanced sexual desire.

2. Ovulation period

Ovulation is a period when progesterone levels gradually decrease, usually between weeks 12 and 18 of a woman's pregnancy. The purpose of this period is for the eggs to be released from the ovaries and into the fallopian tubes to await fertilization. During this period, a woman's body temperature will rise, as will her blood HCG level, and some clear fluid may flow from the vagina.

3. Luteal phase

The luteal phase is a period when progesterone levels continue to rise, usually between the 18th and 24th weeks of pregnancy. The purpose of this period is to allow the fetus to develop and grow in the womb and to maintain the woman's fertility. During this period, a woman's body temperature will rise and there may be some clear fluid flowing out of the vagina, but these are normal physiological phenomena.

Progesterone is one of the important hormones in the female body and plays a vital role in the female reproductive process. Different women may experience changes in progesterone levels at different periods, but no matter which period, if a woman experiences discomfort or abnormality, it is recommended to seek medical treatment in time.
