Thanks for writing to DoctorSpring.com with your health concern.
- Please mention when your last period was.
At times, after stopping birth control, as the body adjusts to the hormones, you might experience spotting / altered bloody discharge.
Endometriosis itself totally explains the pain and the discharge too.
- Can you upload the scan that detailed the cyst and its subsequent bursting ?
The pain could be due to the rupture, as the fluid inside the abdominal ( peritoneal ) surface takes time to get absorbed.
There is no option for this acute phase ( maybe a week ) apart from pain medications(OTC Ibuprofen 400 mg, twice a day with food, for 5 days), a hot water bottle and some fortitude.
If the pain persists beyond a week, you need to see your doctor to rule out an endometriosis flare up.
Feel free to discuss further.
All the best.
