i totally understand your situation. if the bleeding has not responded to deviry (medroxy progesterone) then i would suggest you take her to the hospital and get her admitted. she would need some blood work done to see her blood parameter also would require injectable progesterones in addition to tranexamic acid (blood clotting medicines). if that also does not help then she would require injectable estrogen. meanwhile the ultrasonography and blood work should give an indication as to why this sudden non-stop bleeding occurred. do not leave it undiagnosed as bleeding so heavily in that age group is not a good sign and might be due to an underlying serious issue. for further information consult an obstetrician and gynaecologist online --> <link>
