[20F] Experiencing abdominal pain, headaches, and menstrual irregularities

What might be happening

Based on the information you've provided, possible diagnoses include:

• Gastroenteritis: This is an inflammation of the digestive tract, often caused by a viral or bacterial infection. Symptoms can include abdominal pain, nausea, vomiting, and diarrhea. Treatment typically involves rest, hydration, and over-the-counter medications to manage symptoms.
• Gallstones: These are hard deposits in the gallbladder that can cause pain in the right side of the abdomen. Treatment may involve medication to dissolve the stones or surgery to remove the gallbladder.
• Appendicitis: This is an inflammation of the appendix, a small organ on the right side of the abdomen. Symptoms can include pain in the right lower abdomen, nausea, vomiting, and loss of appetite. This is a medical emergency and requires immediate treatment, usually surgery to remove the appendix.
• Kidney stones: These are hard deposits made of minerals and salts that form inside your kidneys. Symptoms can include severe pain in the side and back, below the ribs, pain that radiates to the lower abdomen and groin, pain that comes in waves and fluctuates in intensity, pain on urination, pink, red or brown urine, cloudy or foul-smelling urine, nausea and vomiting, persistent need to urinate, urinating more often than usual, fever and chills if an infection is present, urinating small amounts of urine. Treatment involves pain relievers and drinking lots of water to help pass the stone. Medical procedures may be required to remove or break up larger stones.
• Pregnancy: Given your history of unprotected intercourse, missed periods, tender breasts, and nausea, it's possible that you could be pregnant. Home pregnancy tests can sometimes give false negatives, so you might want to consider getting a blood test or ultrasound for a more definitive answer.

What you can do

1. Seek immediate medical attention: Given the severity and duration of your symptoms, it's important to seek medical attention as soon as possible. If you don't have a family doctor, consider going to an urgent care clinic or emergency room.
2. Stay hydrated: Drink plenty of fluids to prevent dehydration, especially if you're vomiting or have diarrhea.
3. Rest: Try to get plenty of rest to help your body recover.
4. Avoid triggers: If certain foods or activities seem to make your symptoms worse, try to avoid them.

What you should look out for

• Worsening symptoms: If your symptoms get worse or don't improve, seek medical attention immediately.
• Fever or chills: These could be signs of an infection, which would require immediate medical attention.
• Blood in your stool or urine: This could be a sign of a more serious condition and should be evaluated by a healthcare provider as soon as possible.
