This could be the menstrual phase, when uterine lining sheds to start a fresh. Or it could be the fertile phase following menstruation.
The lining of the uterus is shed during the menstrual phase of the menstrual cycle. This is when the body sheds the built-up uterine lining in the absence of a fertilized egg, resulting in menstrual bleeding.
About once a month, the uterus grows a new, thickened lining (endometrium) that can hold a fertilized egg. When there is no fertilized egg to start a pregnancy, the uterus then sheds its lining. This is the monthly menstrual bleeding (also called menstruation or menstrual period). The MC is measured from the first day of menstrual bleeding, Day 1, up to Day 1 of your next menstrual bleeding. Although 28 days is the average cycle length, it is normal to have a cycle that is shorter or longer.
Spotting before your period is just very light menstrual flow, it's the process of the uterus lining shedding starting - once it gets under way the bleeding becomes heavier.
During the menstrual cycle, the uterus prepares for a possible pregnancy by building up its lining (endometrium). If fertilization does not occur, the uterus sheds this lining during menstruation. The hormones involved in the menstrual cycle regulate these changes in the uterus.
The lining of the blood passing out of the vagina is known as a woman's monthly period. It is natures way to strip the old lining of the Uterus that failed to be needed on the woman becomes pregnant. The lining is rebuilt (renewed) to prepare for a possibly future pregnancy.
The uterus has 3 layers: Endometrium. This is the inner lining. It is shed during your period.
The lining of the uterus shed during the menstrual cycle is called the endometrium. It is the innermost layer of the uterus that thickens in preparation for potential pregnancy and is shed if fertilization does not occur.
The uterus lining deteriorates during menstruation. The menstrual flow is the uterine lining that is shedding after pregnancy does not occur.
Between days 1 to 6 of the menstrual cycle, the uterus is in the menstrual phase, characterized by the shedding of the endometrial lining. This occurs due to a drop in hormone levels, primarily estrogen and progesterone, leading to menstrual bleeding. The uterus is in a state of recovery, preparing for the next cycle as the endometrial tissue is rebuilt in the following phase. By the end of this period, the uterine lining begins to thicken in response to rising estrogen levels.
