[31F] With missed period and mild breast tenderness

What might be happening

Based on the information you have provided, here are some possible explanations for your symptoms:

• Pregnancy: Even though your initial pregnancy test was negative, it's still possible that you could be pregnant. Sometimes, it takes a bit longer for the pregnancy hormone (hCG) to reach detectable levels. Symptoms like a missed period, breast tenderness, nausea, and lower abdominal cramping are common early signs of pregnancy.

  • Testing: Taking another pregnancy test today, as you mentioned, would be a good idea. If it's still negative and your period doesn't start, you may want to consult your healthcare provider for further evaluation.

• Side Effects of Metformin: Metformin can cause gastrointestinal symptoms such as nausea and upset stomach, which you are experiencing. While it's less common, metformin can also affect menstrual cycles, especially in the initial months of starting the medication.

  • Management: These side effects often improve over time. Eating smaller, more frequent meals and taking metformin with food can help reduce nausea.

• Hormonal Imbalance: Starting a new medication like metformin can sometimes cause temporary hormonal imbalances, which might explain your missed period and breast tenderness.

  • Testing: Your healthcare provider may recommend blood tests to check your hormone levels if your period remains irregular.

What you can do

1. Take Another Pregnancy Test: Since your period is 9 days late, taking another pregnancy test today is a good step. If it's positive, schedule an appointment with your healthcare provider to confirm the pregnancy and discuss next steps.
2. Monitor Symptoms: Keep track of your symptoms, including any changes in your menstrual cycle, breast tenderness, nausea, and abdominal pain. Using MDandMe to journal your symptoms can help you track your progress and provide valuable information to your healthcare provider.
3. Manage Nausea: To help alleviate nausea, try eating smaller, more frequent meals and avoid foods that are greasy or spicy. Taking metformin with food can also help.
4. Stay Hydrated: Ensure you are drinking plenty of water, especially if you are experiencing nausea and a lack of appetite.
5. Consult Your Healthcare Provider: If your symptoms persist or worsen, or if your next pregnancy test is negative and your period still doesn't start, make an appointment with your healthcare provider for further evaluation.

What you should look out for

• Positive Pregnancy Test: If your next pregnancy test is positive, contact your healthcare provider to confirm the pregnancy and discuss prenatal care.
• Persistent or Worsening Symptoms: If your nausea, abdominal pain, or breast tenderness worsens or doesn't improve, seek medical advice.
• Severe Symptoms: If you experience severe abdominal pain, heavy bleeding, or any other concerning symptoms, seek medical attention promptly.
