Hello. My name is Vee a 50 years old woman with a very heavy irregular period. After I had a ultrasound, the result were a cysts of 4.5 cm on the left ovary, and a 10 cm fibrosis... I am on norethisterone, 5 mg , three times a day for 10 days but the day I stop take it, my period is started again and again. My own doctor, from Romania, ( now I live in the UK) prescribed me Duphastone and advised me to take the pills in the same time with norethisterone , but the Dr. here said isn't necessary. I am very confused, depressed, tired of loosing so much blood and my hemoglobin cones in a very lower point meaningly 6. Please kindly advise me better, as I feel myself list of these interminable period. Thank you in advance. Vee.
