What does it mean if your nipples have been and are very sensitive for the past few weeks you missed period last week?

There are several reasons why your nipples may be sensitive and you missed your period last week. Some possible explanations include:

1. Hormonal changes: Hormonal fluctuations during the menstrual cycle can cause breast tenderness and nipple sensitivity. This is especially common during ovulation (when an egg is released from the ovary) and in the days leading up to menstruation.

2. Pregnancy: If you are pregnant, hormonal changes can also cause breast tenderness and nipple sensitivity. This is often one of the earliest signs of pregnancy, along with a missed period.

3. Breast cysts or lumps: Breast cysts or lumps can cause breast pain and nipple sensitivity. These are usually benign (non-cancerous) and can be caused by hormonal changes or other factors.

4. Medications: Some medications, such as oral contraceptives, antidepressants, and certain fertility drugs, can cause breast tenderness and nipple sensitivity as side effects.

5. Underlying medical conditions: Certain medical conditions, such as thyroid problems, pituitary gland disorders, and certain types of cancer, can also cause breast tenderness and nipple sensitivity.

However, it's important to note that breast tenderness and nipple sensitivity can be caused by a variety of factors, and it's not always possible to determine the exact cause without further evaluation by a healthcare provider. If you are experiencing persistent breast tenderness or nipple sensitivity, or if you have missed your period, it is advisable to consult with a healthcare professional to determine the cause and receive appropriate treatment or advice.
