Menstruating is the uterus basically not being pregnant and therefor getting rid if the uterine lining. When pregnant there is a fertilized egg and the uterus will protect it with the uterine lining.
The endothelial cells lining the uterus are breaking down and being sloughed off, to prepare for the next cycle. If an egg had been successfully fertilized, a hormonal surge would have preserved the uterine lining in preparation for implantation.
Some women have light bleeding during their pregnancy but it is not a period, a menstrual period is the shedding of the uterine lining - if the uterine lining sheds during pregnancy the embryo or fetus would be miscarried.
Your period is the breakdown of the uterine lining. Once a pregnancy is established by the embryo implanting in the uterine lining, the hormone hCG and progesterone kick in to prevent the breakdown. While pregnant the lining does not break down because it is being used to support the placenta and fetus.
After traveling through the oviduct, eggs are typically released into the uterus, where they may be fertilized if sperm are present. In birds, the egg is then encapsulated in layers of albumen, membranes, and a hard shell before being laid. In mammals, if fertilization occurs, the egg implants in the uterine lining to develop into an embryo. If not fertilized, the egg is eventually expelled from the body.
False.It is physically impossible to get your menstruation cycle (period) while you are pregnant. The reason being that your period happens because eggs are being released from your ovaries. Your uterus creates a cushioning wall for that egg, if it ever happened to be fertilized, thus getting you pregnant. If the egg is not fertilized, the uterus lining is no longer needed so you shed it in the form of blood through your vagina. This is your period. When you get pregnant, the egg and sperm untie to make a baby, and you need the cushioning uterus lining so your body does not shed it.
the hormone FSH ( Follice Stimulating Hormone) triggers the menses (period) in a healthy female. During the menses, the uterine lining is being shed.
Actually removal of all your ovaries does stop the period. Without any eggs present, there's no reason for the uterine lining to shed since it is caused by the eggs not being fertilized in time. No eggs in the first place, no need to shed the egg + uterine lining later.
The tissue that you see in your menstrual flow isn't skin, it is most likely the uterine lining. It's normal to see larger pieces of uterus lining being shed in your menstrual flow on heavier days of your period.
In theory you would be at your heaviest during menstruation. This is because of the uterine lining that is being shed and because in theory you'd be bloating.
Synthetic estrogen and progesterone in birth control pills work by inhibiting ovulation, thickening cervical mucus to prevent sperm from reaching the egg, and thinning the uterine lining to make it difficult for a fertilized egg to implant. These actions collectively help prevent pregnancy by disrupting the normal reproductive process.
There is no need to worry... The shedding of your uterine lining is what causes our menstral periods. With the Depo shot, it PREVENTS the lining from being created therefore there is no shedding that needs to happen and no blood that needs to go anywhere. Hope this helps... This is the EXACT answer that my gyne gave me! :)
