[21F] Experiencing prolonged spotting and intermittent cramps

What might be happening

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

• Hormonal Imbalance: Errin is a progestin-only birth control pill. It works by changing the cervical mucus and the lining of the uterus, and by changing the way the ovaries release eggs. Spotting and cramping are common side effects, especially in the first few months of use.

• Pregnancy: Although you're on birth control, no method is 100% effective. Spotting and cramping can be early signs of pregnancy.

• Infection: Certain infections, such as sexually transmitted infections, can cause spotting and cramping.

• Polycystic Ovary Syndrome (PCOS): This condition causes hormonal imbalances that can lead to irregular periods, spotting, and cramping.

What you can do

1. Continue to monitor your symptoms. If the spotting continues or the cramping becomes more severe, you should seek medical attention.

2. Consider taking a pregnancy test. Even though you're on birth control, it's still possible to become pregnant.

3. If you're sexually active and haven't been tested recently, consider getting tested for sexually transmitted infections.

What you should look out for

• Severe abdominal pain
• Heavy bleeding (soaking through one pad or tampon every hour for several hours)
• Fever or chills
• Dizziness or fainting
