Hi, I Am 39 Of Age And Ive Got 2

Hi, I am 39 of age and Ive got 2 kids and undergone tubal ligation. after 11 years of my tubal ligation am still suffering for heavy menstrual bleeding with menstrual cramps... 3 mos ago I decided to have a check up ... I have undergone IV ultrasound and found out that I have a polyps in my uterus (cancer in the uterus) , I undergone 2nd opinion but the 2nd gynecologist but told me that it might be not a polyps but let me drink the qliara pills for my heavy menstrual bleeding. Ive drunk the pills everyday without missing it but the effect was at first mos. my menstrual heavy bleeding turns to like a brown spot and same with the 2nd month.. like I dont consider it a menstrual period ... here comes the 3rd month... i experience symptoms of having my menstrual period like the 1st and 2nd month.. but at this time I still dont have the period... Ive try contacting my gubecologist but she/he is out of the country... I am worried since it might have effect on my polyps in the uterus... should i stop drinking the pills?
