The second half of the female cycle
In the transformation phase, also known as the luteal phase, the empty follicle in the ovary is transformed into the corpus luteum.
The corpus luteum (the follicle from which the egg bursts) grows on the surface of the ovary and causes it to produce progesterone. The increase in progesterone signals the body to keep the lining of the uterus intact. It also signals the pituitary gland, to no longer produce FSH and LH, which ensures that only one egg is released at a time into the uterus. Estrogen levels continue to rise. Towards the end of the cycle, if the egg has not been fertilized, the corpus luteum is reabsorbed into the body. Progesterone production will soon come to a halt as a result. Testosterone increases towards the end of this phase. Towards the end of your cycle, physical energy decreases. You may notice PMS symptoms – such as bloating, irritability, headaches, mood swings and cravings. Try to honour your body’s signals by resting more and focusing on keeping your blood sugar levels stable.
If the egg cell is successfully fertilised, implantation into the lining of the uterus would take place. If, however, the egg cell has been nudged through the fallopian tube without having met a sperm, the corpus luteum breaks down and the production of progesterone is reduced. The same applies to estrogen. Menstruation then starts and the cycle begins all over again.
To be more specific, progesterone production decreases with the disappearance of the corpus luteum. This is what triggers menstruation a.k.a. the shedding of the uterine lining. Estrogen production reaches its peak and then falls again. That’s stimulating the hypothalamus to get ready for another cycle of ovulation.
A combination of brown spotting and cherry-red bleeding characterizes this phase. You may also experience cramping, back pain, tiredness and cravings. Sometimes you may feel a sense of relaxation and relief while your estrogen peak passes.
