Continuous bleeding. About the report.

This is about my mom. Age 39yrs old. She normally has very light periods that lasts for 3 days only. For the last 2 months she's been bleeding for more than 10 days and also heavy. She got her period on nov 19th started with light brown spotting till 2 days and turned into a heavy period after that. From nov 19th she's been bleeding till now,it is so heavy like she kept on changing sanitary pads 3-4 times a day sometimes it is soaking through her clothes. She is a working woman who is a bank manager in SBI bank. Her shifts will be more than 12hrs sometimes and work load is insane. i dont know if the bleeding will be related to stress or something but she doesn't have time to go to hospital and I am worried about her. She's been becoming weak from the day her period started and also so much of back pain and stomach pain is coming. Last month she went for a pap smear test and i would like to attach the test report here please tell me what to do and also about the report. Thank you.
