Brief Answer: NEED PROPER INVESTIGATION. CONSULT WITH DOCTOR. Detailed Answer: Hello, Thanks for writing to us. Heavy bleeding with clots or lumps following long time missed period may be due to PCOD (Poly Cystic Ovarian Disease), Hypothyroidism, Over weight, Hormonal imbalance, early miscarriage (as you involved in unprotected sex), uterine fibroid or polyp etc. Here, I suggest to undergo one blood test for beta-hCG to rule out pregnancy or miscarriage. Supportive investigation like Pelvic Ultrasound Scan, Hormone test, blood prolactin level etc are required to rule out the exact cause and pinpoint the diagnosis. Proper treatment depends on diagnosis of the case. Therefore, you must consult with your gynecologist for clinical examination and relevant tests as mentioned above. Kindly, procure a complete prescription from your doctor. In the mean time, you would take healthy balanced diet with IRON supplement, drink more fluid or water to stay hydrated, take PARACETAMOL to reduce fever and body ache, maintain genital hygiene properly and take adequate rest. Hope, I have answered your query. Let me know, if you need any clarification. Wish your good health and take care yourself.
