[27F] Experiencing brown discharge and lower back cramps

What might be happening

Based on the information you've provided, possible explanations for your symptoms include:

• Ovulation or pre-menstrual symptoms: Some women experience lower back pain and brown discharge (which is old blood) around the time of ovulation or just before their period starts. This is usually normal and doesn't require treatment unless it's causing significant discomfort or is accompanied by other concerning symptoms.

• Implantation bleeding: This can occur in early pregnancy when the fertilized egg attaches to the lining of the uterus, resulting in light bleeding or spotting. This is typically accompanied by mild cramping and the discharge is usually a light or dark brown color.

• Sexually Transmitted Infections (STIs): Certain STIs, like chlamydia or gonorrhea, can cause abnormal vaginal discharge and lower back pain. However, these are usually accompanied by other symptoms such as burning during urination, pelvic pain, or vaginal itching, which you did not report.

• Side effects of medications: Both Lithium and Seroquel can have side effects that might include changes in menstrual cycle or discharge, though this is less common.

What you can do

1. Monitor your symptoms: Keep track of your menstrual cycle, any changes in your symptoms, and any potential triggers. This information can be helpful for your healthcare provider.

2. Practice safe sex: Use condoms during sexual intercourse to reduce the risk of STIs.

3. Stay hydrated and maintain a healthy diet: This can help manage your back pain and overall health.

4. Consult a healthcare provider: Given your symptoms and recent unprotected sex, it would be a good idea to consult a healthcare provider. They can perform a physical examination, order tests if necessary, and provide appropriate treatment.

What you should look out for

Seek immediate medical attention if you experience:

• Severe lower back pain
• Heavy vaginal bleeding or discharge with a foul odor
• Fever or chills
• Severe abdominal or pelvic pain
• Signs of pregnancy (missed period, breast tenderness, nausea)
