Presentation Transcript
Day 1: Menstruation begins (this is often called having your period ).
Lining of the uterus (endometrium) is no longer needed so it sheds through the vagina releasing blood, mucus, and tissue.
Menstruation usually lasts anywhere from 3-10 days.
Hormones send a signal to your body to begin thickening the lining in the uterus (endometrium).
Lining of the uterus (endometrium) continues to build up and prepares to nourish a fertilized egg.
Hormones continue to rise, triggering an egg to release from one of your ovaries.
Ovaries release a mature egg which travels down the fallopian tube for approximately 24 hours.
The egg can only be fertilized when traveling through the fallopian tube.
The egg reaches the uterus around day 14 of the cycle (but can be different for everyone).
If the egg is fertilized while in the fallopian tube, the egg will attach to the uterine wall and pregnancy can occur. If not, the egg will begin to dissolve in the uterus.
If pregnant, the body will increase hormone production over the next 10 days and menstruation will not occur.
If not pregnant, hormone levels decrease over the next 10 days and will trigger menstruation (a period).
