Premenstrual Syndrome (PMS)

PMS is common in women and girls, with symptoms occurring in the days leading up to their periods.
Symptoms include physical and emotional discomfort.
Examples of symptoms: tiredness, backaches, sore breasts, headaches, constipation, diarrhea, food cravings, depression, irritability, trouble concentrating.
PMS symptoms are usually at their worst during the 7 days before the start of the period.
Symptoms disappear after the period starts.

The Monthly Cycle

The average monthly cycle for an adult woman is 28 days, but can vary from 23 to 35 days.
The cycle includes ovulation.

Fertilization of an Egg

Fertilization occurs if a female and male have sex within a few days of the female's ovulation.
Millions of sperm are released during ejaculation.
Only one sperm is needed to fertilize the egg.
The fertilized egg travels to the uterus.

Blastocyst Development

5-6 days after fertilization, the fertilized egg is now a blastocyst.
The blastocyst is about the size of a pinhead.
It is a hollow ball of cells with fluid inside.
The blastocyst burrows into the lining of the uterus (endometrium).

Implantation

The blastocyst burrows into the endometrium a process called implantation.
Implantation is aided by hormones (estrogen) which makes the endometrium thick and rich with nutrients.
Progesterone, another hormone, keeps the endometrium thick and rich with blood.
