Yes!
Menstruation
Yes. Ovulation can occur irregularly, at times, and implantation of the fertilized ovum in the fallopian tube does not always trigger cessation of menses immediately.
The female hormone that prepares the uterus for the implantation of a zygote is progesterone. It is produced by the corpus luteum after ovulation and helps thicken the uterine lining (endometrium), making it receptive for a fertilized egg. If implantation occurs, progesterone levels remain elevated to support the early stages of pregnancy. If implantation does not occur, progesterone levels drop, leading to menstruation.
Menstruation occur at the age of 9 to 16 years old
In your cycle, implantation bleeding will likely occur several days after the egg implants. This could be anywhere from midway through your cycle, all the way up until you were supposed to start your period.
No.
Yes. Menstruation will still occur with out ovulation
No, menstruation does not occur if the egg is fertilized. Instead, the fertilized egg implants in the uterus to begin pregnancy. If fertilization does not occur, then the uterine lining sheds during menstruation.
yes
No, implantation is necessary for a pregnancy to occur. If a fertilized egg does not implant into the uterus, pregnancy cannot proceed. The shedding of the uterine lining during a period signifies that implantation did not occur.
Menstruation typically occurs about 14 days after ovulation.
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.
