When your period is unusually short, here are the top reasons why.
Is it common to only have periods for two or three days when your menstrual cycle is normally longer?

Your menstrual cycle reveals a lot about your health. Any abnormality should not be overlooked if it indicates a problem with your reproductive health. Every woman has a particular menstrual cycle, and her periods may last anywhere from 2 to 7 days depending on it.
While heavy and prolonged periods may indicate illnesses such as pelvic inflammatory disease or blood problems, abnormally short periods coupled with other discomforts may indicate early pregnancy loss, menopause, or even PCOS.
During the first trimester of pregnancy, you may have light bleeding or spotting.
While you may believe your periods have been shorter than usual, this might be a symptom of early pregnancy. Light spotting or bleeding after conception, known as implantation bleeding, can occur 10-14 days after conception and is considered normal. On the other side, it might also be a miscarriage.
It might also be menopause.
Before menopause, which normally occurs around the age of 50, a woman’s menstrual cycle changes as well. Around this time, some women may skip their periods or have shorter periods. If you’re having hot flashes, having trouble sleeping, having night sweats, or having vaginal dryness, you may be approaching menopause.
It could be a symptom of PCOS (Polycystic Ovary Syndrome)
PCOS, an indication of hormonal imbalance, might be the cause of ovulation problems or a change in a woman’s menstrual cycle duration.
PCOS is characterized by irregular menstrual cycles, infertility, excessive hair growth, obesity, oily skin, and fluid-filled sacs on the ovaries, according to the expert.
In a nutshell, if you are experiencing shorter periods than usual, as well as other symptoms, you should see a doctor.
