[26F] Experiencing breast tenderness, lower back pain, and nausea

What might be happening

Based on the information you've provided, the following conditions could be causing your symptoms:

• Premenstrual Syndrome (PMS): This is a common condition that can cause a variety of symptoms in the two weeks before your period, including breast tenderness, fatigue, and changes in appetite. The knot you felt in your breast could have been a cyst, which can also be related to your menstrual cycle.

  • Treatment often involves lifestyle changes such as regular exercise, a balanced diet, and stress management. Over-the-counter pain relievers can help with physical symptoms, and some people find relief with hormonal birth control.

• Pregnancy: Despite a negative pregnancy test, it's still possible that you could be pregnant, especially if the test was taken early. Symptoms can include breast tenderness, changes in appetite, nausea, and fatigue.

  • Confirming a pregnancy usually involves a blood test or ultrasound at a doctor's office.

• Hormonal Imbalance: Conditions such as Polycystic Ovary Syndrome (PCOS) or thyroid disorders can cause hormonal imbalances that lead to irregular periods, breast tenderness, changes in appetite, and fatigue.

  • Treatment typically involves medication to manage hormone levels and symptoms.

What you can do

1. Retake a home pregnancy test: If it's been a week or more since your last test, you might want to take another one to be sure. Follow the instructions carefully for the most accurate results.
2. Keep track of your symptoms: Note when they occur, how severe they are, and anything that makes them better or worse. This can help you and your doctor identify patterns and potential triggers.
3. Maintain a healthy lifestyle: Regular exercise, a balanced diet, and adequate sleep can help manage many of the symptoms you're experiencing.
4. Consult a healthcare provider: Given the range and persistence of your symptoms, it would be a good idea to see a healthcare provider for a more thorough evaluation.

What you should look out for

Seek immediate medical attention if you experience any of the following:

• Severe abdominal or pelvic pain
• Heavy vaginal bleeding
• Difficulty breathing or chest pain
• Severe nausea or vomiting
• Any other symptoms that are severe or concerning to you
