What is the difference between menstruation and menstruation cycle?

Menstruation is one of the phases of the menstrual cycle, whereas the menstrual cycle is the entire reproductive system.

What happens in the ovaries during menstruation?

During menstruation, the ovaries do not play a direct role. Menstruation is primarily controlled by hormonal changes in the uterus. The ovaries release an egg during ovulation, which typically occurs around the middle of the menstrual cycle. If the egg is not fertilized, hormone levels drop, leading to the shedding of the uterine lining and the start of menstruation.


Why does your period start again the week after you had your period?

Menstruation is a very specific bodily function, it's not normal for you to have gone through an entire menstrual cycle in such a short space of time. The bleeding you've been experiencing may not have been menstruation but bleeding as a result of hormonal imbalance. It would be a good idea to talk to your doctor about this to ensure everything is okay.

If You start having PMS SYmptoms before implantation are you going to get period?

Okay. PMS (premenstrual syndrom) refers to a Syndrom caused by a woman's reaction to hormonal body changes just prior to menstruation. It usually starts around day 25 of the menstrual cycle. This indicates the body is about to experience menstruation. When an egg implants, there are hormonal changes in the body which prevent menstruation, and prepare the body to support the growing embryo. Implantation usually occures around day 14 of the menstrual cycle. If one experiences implantation, then hormones will be released preventing menstruation. Therefore, the body will not experience the hormones which begin menstruation. If you are having true PMS, then you are going to menstruate (have a period), and nothing was implanted, or will implant. As the uterus readies for menstruation, it becomes a hostile environment for the egg.

How long does norethindrone take to start your menstrual cycle?

Norethindrone doesn't start your menstrual cycle. Norethindrone is a progesterone medication typically used to delay menstruation - you take it three days before menstruation in order to prevent the progesterone drop that would normally trigger menstruation. Once you stop takine Norethindrone the drop in progesterone triggers bleeding - this normally occurs within 24 hours of stopping the pill. This bleeding may trigger the menstrual cycle if there have been problems with abscent menstruation, but that is not always the case - it depends on why cycles have stopped.
