I am 20 years old. My periods last for only 2 days, is it normal?

Question

Normally, a woman’s cycle is about 4 weeks, where a woman ovulates at mid cycle and menstruates for 4 to 7 days, approximately 14 days after ovulation. The duration of a normal period may also differ among various women, but when a woman’s period only lasted 2 days, the sudden short period may lead them to worry whether something else is wrong, or wonder if they are pregnant.
It is not normal to have a period of 2 days. For many women, a normal menstrual period can last 4 to 6 days. Just as every woman is unique, every woman's menstrual period is also unique. After a few years' of monthly menstrual bleeding, most women have a feel for their period's duration, frequency, and flow. When something out of the ordinary happens, such as a sudden and short menstrual period, it's natural to wonder what's going on.
Reasons =
1.Stress
A woman’s body is well adapted to dealing with everyday short term stress, but long term stress can shorten or lengthen your menstrual cycle, and make your periods more painful. Moreover, high stress levels make bacterial vaginosis more likely. Try alleviating the stress through regular exercise.
2.Estrogen Changes
Estrogen is the hormone responsible for the changes that may occur during your menstrual cycle, and any changes in your body's level of estrogen can disrupt the normal pattern of your period. That's why women approaching menopause and young girls going through puberty, commonly have irregular periods. Any changes in estrogen levels at any stage of life can affect the length and regularity of your periods.
3.Birth Control Pills
4.Rapid Weight Changes
Rapid weight loss or gain can lead to sudden changes in your cycle, including irregular periods or not getting your period at all. Even though a low body weight is a common cause of irregular or missed periods, being overweight can cause same problems. The good news is that your period usually returns to normal once your body returns to its healthy weight.
