Why does the lining of the uterus build up between day 5 and 14?

You can think of the uterus as a garden. It builds up the lining like a gardener adding mulch so when she plants seeds, they will grow well. The same goes for the newly fertilized egg.

Why does the lining of the uterus decrease between day 1 and day 5?
Because its when ovulation occurs and the inside liquids "eat" at the uterus lining.

What days during the mestrual cycle does the lining of the uterus build up?
the uterine lining builds-up during the proliferate phase of the menstrual cycle. Everyone's menstrual cycles are different, but during a 28 day cycle this phase would be around days 16-28.
Why do the lining of the uterus thickens from around day 5 until some days after the egg has been released?
The lining of the uterus thickens because it goes into a protective mode. This is to protect the egg should it become fertilized. Sometimes this can cause cramping during the menstrual cycle.
When which hormone falls it causes the uterus lining to breakdown?
The uterine lining begins to breakdown when the egg of a female is not fertilized by the sperm of a male. This occurs on day one of the menstrual cycle.
What happens after girls have their periods?
A woman's cycle is normally 28 days (some can be shorter or longer) average. When she doesn't get pregnant the bodies hormones give a message to the body to get rid of the lining of the uterus. The first day of a period is day one and so on. About day 14 of a cycle a new ovum is released and in this time a girl/woman can get pregnant. Since sperm can live 5-6 days in the uterus having sex from day 11 to 18 can lead to pregnancy. Again, if no pregnancy is produced the body starts all over to get rid of the lining of the uterus and the cycle continues month after month.
What happens in a 28 day menstrual period and what kind of phases occur in a period?
About once a month, the uterus grows a new, thickened lining (endometrium) that can hold a fertilized egg. When there is no fertilized egg to start a pregnancy, the uterus then sheds its lining. This is the monthly menstrual bleeding (also called menstruation or menstrual period). The MC is measured from the first day of menstrual bleeding, Day 1, up to Day 1 of your next menstrual bleeding. Although 28 days is the average cycle length, it is normal to have a cycle that is shorter or longer.
How can you use RU 486?
Mifepristone (RU486) is given to you by the doctor so the embryo dies. The next day he gives you Misoprostol so the embryo and lining of the uterus comes out and completes the abortion.
Why do you only bleed slightly for about 1 day on your pill free week?
It is the bonus side effect from taking hormonal BCP. The lining in the uterus is not as built up so there is less to shed.
When is an egg considered an embryo?
It takes 1-3 days for a egg to get fertilized and then it's called a zygote. It then takes 3-5 days until the zygote enters the uterus. In the uterus, the cells continue to divide and becomes blastocyst which attaches to the lining of the uterus. This is called implantation and is completed by day 9-10. The next step it's a embryo.
Can you get pregnant on the day ovulation starts?
Yes, you can get pregnant if ovulation starts because this means that the egg which is ready for fertilization is now released. It can live up to 12 to 24 hours before it will be absorb in the lining of the uterus.
What occurs during the menstrual cycle?
The cycle starts with menstruation. From day 1 to 5 of the cycle, a drop in the level of the hormone progesterone causes the uterus lining to break down (menstruation), it is released as blood through the vagina. From day 6 to 10, The ovaries produce estrogen which will cause the uterus lining to rebuild. Another hormone FSH ( follicle stimulating hormone) produced in the brain (especifically, the pituitary gland) causes one of the follicles in the ovary to mature. A follicle contains an egg cell. From day 11 to 15, the level of estrogen drops and the pituitary gland in the brain produces a hormone called LH (lutenizing hormone), which will trigger the release of the egg cell from the matured follicle (this is called ovulation). From day 16 to 20: the remains of the follicle in the ovary (now called Corpus luteum) will secrete progesterone, which will keep the uterus lining thick, in case fertilization occurs between a sperm cell and the newly released egg cell. From day 17 to 27, the Corpus Luteum breaks down causing a drop in the level of progesterone, which will trigger menstruation and the cycle re-starts.
