It's been over a week since my period ended, but I'm noticing discharge mixed with blood (warning: photo attached).

Given the image and your history of antibiotic use, here's a breakdown of potential causes and what you should consider: Possible Causes: 1. Spotting: Spotting is light bleeding outside your regular period. Since it's been over a week since your period, this is a strong possibility. 2. Hormonal Imbalance: Antibiotics can sometimes indirectly affect hormone levels, potentially causing irregular bleeding. 3. Infection: The discharge combined with blood could indicate a vaginal infection. Antibiotics can disrupt the natural vaginal flora, making you more susceptible to yeast infections (candidiasis) or bacterial vaginosis (BV). BV can cause a thin, grayish-white discharge with a fishy odor, sometimes mixed with blood. 4. Cervical Polyps: These are benign growths on the cervix that can bleed, especially after intercourse. 5. Retained Products of Conception: Although less likely if you aren't pregnant, this should be considered 6. Other Uterine Problems: Less common, but uterine fibroids or other growths can sometimes cause abnormal bleeding. Recommendations: * Monitor: Keep track of the amount, color, and consistency of the discharge. Note any associated symptoms like itching, odor, or pain. * Probiotics: Since you've taken antibiotics, consider taking oral probiotics or using vaginal probiotics to help restore your vaginal flora. Choose a brand specifically formulated for vaginal health. * Hygiene: Avoid douching, as it disrupts the vaginal flora. Use gentle, unscented soap to wash the external area. * When to Seek Medical Advice: If the bleeding becomes heavier (soaking a pad in an hour), you develop a fever, severe abdominal pain, or the discharge has a foul odor, seek medical attention immediately. It is important to consult a doctor, especially with this type of image.
