I am 42 yr old . I am having periods within every 20 days since last 3 months . Have started my period again with very little bleed this time but it's almost 12 days now. Got my trans vaginal ultrasound 2 years back, was normal and Pap smear was normal . Had this problem 2 years back , took oral progesterone for some time and periods were normal since last 1 year . Please advice how to stop the bleeding .
