The luteal phase is the period after ovulation when progesterone prepares the uterus for possible pregnancy implantation. It usually lasts about 12–16 days depending on individual cycle hormone balance.
The luteal phase is the second half of the menstrual cycle that begins after ovulation. During this phase, progesterone hormone helps maintain the uterine lining for possible embryo implantation.
Tracking luteal phase length helps in understanding fertility health, hormonal balance, and cycle regularity.
