[19F] With severe lower abdominal pain and missed periods

What might be happening

Based on the symptoms you've described, there are a few potential conditions that could be causing your severe stomach pain and missed periods. Here are some possibilities:

1. Appendicitis: This is an inflammation of the appendix and can cause severe pain in the lower right side of the abdomen. It often requires urgent medical attention and surgery to remove the appendix. Symptoms can include sharp pain, nausea, and sometimes fever.

2. Ovarian Cysts: These are fluid-filled sacs that can form on the ovaries. They can cause sharp, cramping pain in the lower abdomen and may affect your menstrual cycle. An ultrasound is typically used to diagnose ovarian cysts.

3. Ectopic Pregnancy: Although your pregnancy tests are negative, an ectopic pregnancy (where a fertilized egg implants outside the uterus) can sometimes cause severe abdominal pain and missed periods. This is a medical emergency and requires immediate attention.

4. Pelvic Inflammatory Disease (PID): This is an infection of the female reproductive organs and can cause severe abdominal pain, irregular periods, and other symptoms. It often requires antibiotics for treatment.

5. Gastrointestinal Issues: Conditions like irritable bowel syndrome (IBS) or inflammatory bowel disease (IBD) can cause severe abdominal pain and changes in bowel habits. These conditions often require a combination of dietary changes, medications, and sometimes further testing like colonoscopy.

What you can do

Given the severity and duration of your symptoms, it is crucial to seek medical attention as soon as possible. Here are some steps you can take:

1. Visit an Emergency Room: Given the potential for serious conditions like appendicitis or an ectopic pregnancy, you should go to the emergency room immediately. If the pain is too severe to drive, call 911 or have someone else take you.

2. Keep Track of Symptoms: Note any additional symptoms that may develop, such as fever, vomiting, or changes in bowel or urinary habits, and share this information with the healthcare provider.

3. Avoid Eating or Drinking: Until you have been evaluated by a healthcare professional, it may be best to avoid eating or drinking, especially if surgery might be needed.

4. Stay Hydrated: If you are able to drink fluids without worsening your pain, try to stay hydrated, but avoid solid foods until you have been evaluated.

5. Follow Medical Advice: Once you see a healthcare provider, follow their recommendations for tests and treatments. This may include blood tests, imaging studies like an ultrasound or CT scan, and possibly medications or surgery.
