I have done foliculometry on 8th, 12th & 16the day. Folicle size was 22.5, 24.5, 20.5, and ruptured. endometrium thickness 12.5. On 31st day my period started with heavy bleeding, clotting blood is coming frequently. Paining left side. What could be the possible reason for heavy clotting. What would be the possible medication.
