Hi ! Good morning. I am Dr Shareef answering your query. Yes ! You should get yourself reviewed by your treating gynaecologist soon. If I were your doctor, after a clinical examination, I would send the specimen of the discharge for culture and sensitivity test, routine CBC, a serum HCG test, and an ultrasound abdomen if need be. If comes out to be a pelvic infection, the nexplanon might have to be removed for the time being till the infection is cured. Further management would depend on the reports of the investigation. Till then you can go for some kind of anti inflammatory drug for pain and inflammation. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. Wishing you an early recovery. Dr Shareef.
