Hello, I have been prescribed this medicine and the prescription says take Two, three times a day. but it doesn t say for how many days. I have very prolonged bleeding too and all messed up. i am also taking tranaxamic acid 2x 500mg 3 times a day for first 5 days of my period. now i am very confused about how long should i take this norethisterone for. any advice would be really helpfull.
