Had abnormal uterine bleeding too aygestin (norethindrone) for a mth and it helped, I ran out it took a few days for bleeding to come back. What should I do?

Get a refill. Go see your prescribing doctor & get a refill of your Aygestin (norethindrone). Discuss how long you're expected to continue taking this medication. Ask about other options (such as hormonal contraception) & tests to figure out the cause of your abnormal uterine bleeding.
From what i. Understood you have abnormal uterine bleeding and were given hormone that has helped . I think you need to contact your provider and explain what happen and follow instruction and guidance diligently . Good luck.
