One deep and one shallow is a sign of menstruation

The change of one dark and one light breast can indeed be a precursor to menstruation. Many women experience breast changes at different stages of the menstrual cycle, such as breast sensitivity, swelling, and even the appearance of one dark and one light breast. These changes are usually caused by fluctuations in hormone levels in the body, especially the effects of estrogen and progesterone during the menstrual cycle.

During the luteal phase of the menstrual cycle, estrogen and progesterone levels rise in the body, causing breast tissue to grow and water to be retained. This may make the breasts look asymmetrical, or slightly larger on one side than the other. These changes are usually temporary and will fade away once your period starts. If you notice breast changes along with other menstrual symptoms, such as bloating, mood swings, and mild cramping, this could be a sign that your period is approaching.

Of course, while changes in one darker breast and one lighter one are usually normal, if this asymmetry persists or is accompanied by unusual symptoms such as pain or lumps, it is recommended to consult a doctor as soon as possible. This is because breast changes may also be related to other health problems, such as breast inflammation or fibrocystic breast disease, or even in rare cases, breast tumors.

To relieve premenstrual breast discomfort, try wearing a well-fitting bra that provides good support. Maintaining a healthy diet and getting enough exercise can also help relieve symptoms. Some women find that cutting back on caffeine and salt can help relieve breast tenderness. Staying hydrated and drinking plenty of water can also help relieve swelling.

It is important to understand how your body changes. If you feel uncomfortable or have concerns about breast changes during your menstrual cycle, discuss it with a healthcare professional. They can provide you with personalized advice and guidance to help you better understand and manage these physiological changes.
