However, stress, anxiety, poor diet, intense exercise, or weight loss can also cause menstrual delays. In addition, the possibility of pregnancy should always be considered, as well as other causes such as polycystic ovary syndrome, hypothyroidism, or hyperprolactinemia.

What to do: It is recommended to see a gynecologist as soon as possible, because if the bleeding is very heavy, blood loss can lead to anemia or have more serious causes. In these cases, medications such as anti-inflammatories or estrogen-based medications may be needed to help slow the flow. Check out other symptoms of heavy menstruation and how to treat it.
4. Brown menstruation
Brown menstruation similar to coffee grounds, in most cases, does not indicate any problem, usually appearing at the end of the menstrual cycle, as the expelled blood is older and may become brownish.
However, brown menstruation can also occur in women who use a contraceptive implant in the arm, when switching from one oral contraceptive pill to another or due to the use of the morning-after pill. Other causes include stress, pre-menopause or polycystic ovary, but it can also be a sign of miscarriage. Know when brown period is a warning sign.
