Hello I share your concern Looking at your history this could be Infection or inflammation of the urogenital tract Chances of pregnancy can t be ruled out without history of unprotected sex during unsafe period of cycle. I would like further information to help you better like Your age and exposure to unprotected sex in recent past? Is it associated with pain in abdomen or nausea or vomiting? In my opinion you should consult a gynaecologist for physical examination and battery of tests to establish a diagnosis and treatment accordingly Meanwhile maintain good hygiene Have plenty of fluids including lemon water and fresh fruit juices Hot water bath Use condom during sex until you recover fully. Thanks for your question Best wishes
