There is not a scientifically proven way to begin a period early or sooner than it is due. While there are myths that try to advertise different ways to jump start a period, none of them are legitimate, explains Dr. Jen Gunter.
A period is a complicated process that involves multiple stages. The process begins in the brain, where a signal is sent to the ovary to begin producing follicles, which later rupture to release eggs. This causes the lining of the uterus to thicken. When the egg is released, progesterone is released to keep the uterus ready for implantation. If fertilization does not occur, progesterone is no longer released after about 14 days. Without the progesterone, the lining of the uterus sheds and causes bleeding. This cycle takes anywhere from 24 to 32 days to complete. As it is a natural process in the female body, it cannot be sped up, claims Dr. Gunter.
There are a few reasons why a period could come early, however. None of these methods should be used to prematurely begin a period. Things like incorrect use of birth control, extreme stress and young age can cause premature periods, as well as possible hormonal imbalances caused by each condition, notes EmpowHER.com.
