Hi,
According to your description as you are not having bleeding or
vaginal discharge and able to feel the strings, the symptoms you have mentioned may not be related to Mirena.
Cramping
abdominal pain, watery diarrhea and headache these are pointing more towards Gastrointestinal problem like
Gastroenteritis with electrolytes imbalance. Simple
analgesic may not be sufficient to treat the problem.
So, please consult your physician once, get examined. Antibiotics,
probiotic powder, electrolytes replacement can help to decrease the symptoms. Usually Mirena works for 5 years, if the time of period of Mirena is over, you can consult your Gynecologist and can get it removed.
Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Sree Gouri S. R., OBGYN
