Thanks for your help

Dear Carissa: After 3 months, you should have completely recovered from your procedure and should not have irregular bleeding. I suspect you may have suffered a complication such as retained products of conception. This would explain your continued bleeding. I urge you to seek medical attention immediately as the heavy blood loss as already started to take its toll as evidenced by your weakness, frequent headaches and dizziness! A simple ultrasound will confirm my suspicions and repeat surgical procedure will correct the problem.
