Three phases of the menstrual cycle The phases of your menstrual cycle are triggered by hormonal changes.
Menstrual period On Day 1 of your cycle, the thickened lining (endometrium) of the uterus begins to shed. You know this as menstrual bleeding from the vagina. A normal menstrual period can last 2 to 7 days. 6
Most of your menstrual blood loss happens during the first 3 days. This is also when you might have cramping pain in your pelvis, legs, and back. Cramps can range from mild to severe. The cramping is your uterus contracting, helping the endometrium shed. Generally, any premenstrual symptoms that you've felt before your period will go away during these first days of your cycle.
Follicular phase During the follicular phase, an egg follicle on an ovary gets ready to release an egg. Usually, one egg is released per cycle. This process can be short or long and plays the biggest role in how long your cycle is. At the same time, the uterus starts growing a new endometrium to prepare for pregnancy.
The last 5 days of the follicular phase, plus ovulation day, are your fertile window. This is when you are most likely to become pregnant if you have sex without using birth control.
Luteal (premenstrual) phase This phase starts on ovulation day, the day the egg is released from the egg follicle on the ovary. It can happen any time from Day 7 to Day 22 of a normal menstrual cycle. During ovulation, some women have less than a day of red spotting or lower pelvic pain or discomfort (mittelschmerz). These signs of ovulation are normal.
If the egg is fertilized by sperm and then implants in the endometrium, a pregnancy begins. (This pregnancy is dated from Day 1 of this cycle.) If the egg is not fertilized or does not implant, the endometrium begins to break down. After the teen years and before perimenopause in your 40s, your luteal phase is very predictable. It normally lasts 13 to 15 days, from ovulation until menstrual bleeding starts a new cycle. This 2-week period is also called the "premenstrual" period.
Most women have premenstrual symptoms during all or part of the luteal phase. You may feel tense, angry, or emotional; gain water weight and feel bloated; or have tender breasts or acne. A day or more before your period, you may start to have pain (cramps) in your abdomen, back, or legs. It is normal to have less energy at this time. Some women also have headaches, diarrhea or constipation, nausea, dizziness, or fainting.
When premenstrual symptoms make your daily life difficult, you are said to have premenstrual syndrome (PMS). For more information, see the topic Premenstrual Syndrome (PMS).
as u grow old the days for the mesuration cycle will keep reducing but there is no medicine to extend it .
