Hi! Good afternoon. I am Dr Shareef answering your query. All the precautions including birth control pills are not 100% fool proof in protection against a pregnancy if you are sexually active. If I were your doctor, I would advise you for a CBC, a serum HCG test, and an ultrasound abdomen to rule out an unsuspected pregnancy, and any other pelvic adnexal pathology. Apart form this, a rouine/microscopic/culture and sensitivity test would add to the efforts in diagnosing the condition. If all are negative, I would refer you to a gynaecologist to do further needful to make you fit. 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. I wish you an early recovery. Dr Shareef.
