It can have something to do with stress, hormones (something wrong like a cyst or something on an ovary) or too much exercise.
When you become pregnant, your menstrual cycle is delayed for next ten periods. That means you will not get menstrual bleeding till delivery.
The simple answer to this is hormones. A girl or woman's hormones fluctuate significantly during their menstrual cycle causing heightened emotional responses and mood swings.
Regardless of menstruating or not your body will still have the hormones for a positive test.
It depends on the reason your periods stopped. If your hormones are functioning properly you have a period about two weeks after you ovulate, if you are not pregnant.
Normally, women do not have periods or bleeding during pregnancy.
Yes, they can, BUT, only if they have received their periods. Without a menstrual cycle, a pregnancy is not possible.
Ask your doctor.
Yes - thin periods are not an indicator of infertility, however if you are underwieght that will make conception difficult
Your period is regulated by hormones. Green tea does not contain those hormones, or effect your hormones in any way. The only way to regulate periods is through hormones, such as birth control.
It's a shorter way of saying "menstrual period" as opposed to other kinds of periods, such as orbital periods, periods of time, etc. The etymology of the word (Greek) is something along the lines of "Interval, season, time, circuit" etc.
If you are a teenager, it is normal to have "odd" menstrual periods - sometimes heavy, sometimes light, sometimes skipping entirely, sometimes very early. Your hormones will level out as you grow, and your periods will become more regular.
Women have menstrual periods because this is a part of our reproductive cycle. Every cycle we ovulate and the uterus builds-up to prepare for possible pregnancy to care for the fetus, if a woman doesn't fall pregnant then the uterus lining sheds so it can start a fresh next cycle.
