Period Calculator - Stages in a Menstrual Cycle

In the years preceding menopause, a woman's body goes through a range of changes each month to get ready for a prospective pregnancy. An egg develops and is discharged from the ovaries once every menstrual cycle. The uterus' lining thickens over time. If there is no pregnancy, the uterine lining sheds throughout the menstrual cycle, and the cycle resumes. Keeping track of your menstrual cycle is important for various reasons, such as family planning or understanding your reproductive health. Allcalculator.net offers a convenient Period Calculator that can help you predict and track your menstrual cycle. By using the Period Calculator from Allcalculator.net, you can better understand the timing of your cycles, anticipate ovulation, and plan accordingly. This tool simplifies the process and provides valuable insights into your reproductive health.
The four stages of a woman's menstrual cycle are as follows:

• Menstrual stage
• the follicular stage
• the luteal phase, and 
• the ovulatory phase

Each phase's duration might vary from woman to woman and over the course of time.

Menstrual Stage 

The first phase of the menstrual cycle is known as the menstrual phase. At that time, you also begin to menstruate. With Allcalculator.net’s Period tracker, you can keep yourself in the loop with your cycle. 
This stage starts when one egg from the previous cycle is not fertilized. When there hasn't been a pregnancy, the levels of estrogen and progesterone decrease.
Your uterus' thicker lining, which would normally sustain a pregnancy, no longer serves a purpose and sheds via your vagina. During your period, the uterus expels tissue, blood, and mucus.

Follicular phase 

After you ovulate, the follicular phase comes to a close. It starts on the first day of your period (there is some overlap with the menstrual phase).
Follicle-stimulating hormone is first released by your pituitary gland in response to a signal from your brain (FSH). This hormone causes your ovaries to produce 5–20 little sacs called follicles.
Only the healthiest egg will ultimately hatch. The expanding follicle increases estrogen levels, which thickens the lining of your uterus.

Ovulation Stage 

Your ovary produces a mature egg during Ovulation. The fallopian tube directs the egg towards the uterus, where the sperm will fertilize it.
You can only become pregnant during the ovulation period of your menstrual cycle. If you experience any of the following symptoms, you may be ovulating:
a slight increase in basal body temperature thicker, egg-white-like discharge
Ovulation occurs on day 14 of a 28-day cycle, right in the midst of your menstrual cycle. It lasts around 24 hours. The egg will expire or dissolve if it is not fertilized within a day.

Luteal Sage 

As the follicle releases its egg, it changes into the corpus luteum. Progesterone and possibly estrogen are the major hormones released by this structure. The increase in hormones maintains your uterine lining thick and prepared for the implantation of a fertilized egg. The corpus luteum will shrink and resorb if you are not able to conceive. 
Your menstruation will start as a result of reduced levels of estrogen and progesterone. Throughout your period, the uterine lining will shed.
