Hi welcome to the health care magic You have been prescribed trenexemic acid for suspecting dysfunctional uterine bleeding like feature But as bleeding still there you should be investigated with USG pelvis and per speculum examination.... This work up will help in identifying organic causes if present like polyp, cervicitis, fibroid, endometrial hyperplasia, endometriosis etc.. If needed pap smear and Hormonal estimation study also done for further work up You will be prescribed along with trenexa, a drug called primolute N like synthetic progesterone Take care Hope your concern solved With keeping my answer in mind consult gynecologist for examination
