My breasts have swelled for a week and my period hasn't come yet

Many women experience breast swelling before their period. So, what’s going on if my breasts have been swollen for a week but my period hasn’t come yet? In fact, it is very likely that the chest pain is caused by irregular menstruation or an unexpected pregnancy. If you don't have sex, you can wait for a while. If you have sex, it's best to go to the hospital for a check-up to see if you are pregnant.

Menstrual disorders, also known as irregular menstruation, are common gynecological diseases, manifested as abnormal menstrual cycles or bleeding volume, and may be accompanied by abdominal pain and systemic symptoms before and during menstruation. The cause may be organic disease or functional disorder.

1. Abnormal emotions cause menstrual disorders

Emotional abnormalities, such as long-term mental depression, mental tension, or severe mental stimulation and psychological trauma, can lead to menstrual disorders or dysmenorrhea or amenorrhea. This is because menstruation is caused by the hormones secreted by the ovaries acting on the endometrium. The hormones secreted by the ovaries are controlled by the hormones released by the pituitary gland and hypothalamus. Therefore, any abnormality in the function of the ovaries, pituitary gland, or hypothalamus will affect menstruation.

2. Cold stimulation causes oligomenorrhea or even amenorrhea

When women are exposed to cold during menstruation, the blood vessels in the pelvis will contract excessively, which can cause oligomenorrhea or even amenorrhea. Therefore, women should pay attention to preventing cold and avoiding dampness during menstruation in their daily life.

3. Dieting causes irregular menstruation

A girl’s body fat must account for at least 17% of her body weight before she can have her first menstruation, and her body fat must reach at least 22% of her body weight to maintain a normal menstrual cycle. Excessive dieting will cause a large amount of fat and protein in the body to be consumed due to insufficient energy intake, resulting in estrogen synthesis disorders and obvious estrogen deficiency, affecting menstruation, or even causing scanty menstruation or amenorrhea. Therefore, women who pursue a slim figure must not diet blindly.
