Period Calculator

One of the most upsetting experiences that most women have is getting their period right at the start of a vacation or on busy days spent outdoors. For those women who get severe pain and cramps during their period, this can be more than just a minor inconvenience. One way to avoid having to go through that extreme discomfort is using a Period Calculator to plan your activities.

A Period Calculator is a simple tool to help you estimate the start and end date of your next period. Not all women get their period on the same date each month, as it depends on the length of the menstrual cycle.

Another important aspect of a period calendar is determining the time of ovulation as well as the Fertile Period (the time during which intercourse has the highest chance of resulting in a pregnancy). This includes the date of ovulation and 5 days prior to this date. In a 28-day cycle, ovulation typically occurs on the 14th day. 

Tracking your cycle duration over the course of a year will allow you to determine the average duration of your cycle. A normal menstrual cycle can range anywhere between 21-35 days.

A Period Calculator uses the following details.

Note: The date provided by such a calculator is not an exact date. This is an estimation of the most probable time of ovulation and your next period. This method also can only be reliably applied in women who have regular cycles. 

Periods, or the menstrual cycle is a normal, physiological process that occurs in women after the onset of puberty up until menopause. This is a cyclical event, marked by the shedding of the inner lining of the uterus through the vagina. 

The menstrual cycle is delicately maintained by a balance of many hormones in the body, such as oestrogen, progesterone, FSH (follicle stimulating hormone), and LH (luteinizing hormone). These hormones act at different times and set in motion the different events of the menstrual cycle. 

Your menstrual cycle begins on the first day of your period. Normally periods last between 2-8 days. The average menstrual cycle lasts 28 days, but can normally range between 21-35 days. 

During the menstrual cycle, changes occur in both the ovary and the uterus. 

The Ovarian cycle primarily deals with the production and development of the ovum or egg, followed by Ovulation, the event where the developed egg is released and is ready to be fertilised by a sperm cell. If conception does not take place, the egg devolves and atrophies. 

At the same time as this, the Uterine cycle also takes place. The uterus prepares itself for the possibility of a pregnancy. The inner lining (endometrium) grows and proliferates so that it is capable of providing the embryo with nutrition. If pregnancy does not occur, the inner lining sheds in what is known as the period. 

There are several conditions such as PCOS, thyroid disorders, endometriosis, pelvic inflammatory disease, and ovarian and uterine cancers that are associated with irregular periods. Using a Period Calculator may not be reliable in these cases.

Here are the prominent uses of a Period Calculator.
