Generally, menstruation occurs once a month. However, if your cycles are short, there may be months when you have your period not once, but twice, however strange this may seem. While this may be completely normal, it may also be due to hormonal changes that are causing short cycles or bleeding that is not actually menstruation, but may seem as such.
Menstruation is bleeding that occurs as a result of the shedding of the inner lining of the uterus, i.e. the endometrium. The female reproductive system works in a cyclical fashion to produce and release an egg, or to become pregnant. If the woman does not come into contact with sperm, pregnancy does not occur and menstruation arrives approximately 14 days after the egg is released, marking the beginning of a new cycle.
Although cycles are said to be 28 days long, this is only an average; each woman has her own cycle length, which usually ranges from 21 to 35 days. If our cycles are closer to 21 days than to 30 days, mathematically it is perfectly possible for us to sometimes have our period twice in a month.
This tends to happen more in young women, whose bodies are still adjusting at a hormonal level. If your cycles are suddenly shortened for no apparent reason, it is important to go to the gynecologist, as there could be an underlying problem or it could be due to factors such as:
-Extreme weight loss or gain
-Hormonal and/or emotional disorders
In some cases, having two menstrual periods in a short amount of time can cause anemia. Therefore, it is important to go to the gynecologist and inform them about the specific days of your menstruation and all associated symptoms, so that they can identify the cause of the menstrual imbalance.
