i am 65 years old, and right at penetration I have bright red bleeding, which will stop after a while ( like a pouch empted ) and then ther is no bleeing untill another 2 days. I went for ultrasound, I did not need endometrial biopsy, the doctor said the lining of my wall is thin, started me on vagifem suppository, 1 month ago. The bleeding did not stop. How long do I have to wait? can they stop the bleeding with something like laser?
