Hi I Have Had Abnormal Uterine Bleeding, Light Bleeding For

Hi I have had abnormal uterine bleeding, light bleeding for a week then heavy period bleeding for a week.
Went for many ultrasounds and bloodwork all normal except very low vit d. Inflammatory smear and did a cryosurgery. Did other infections tests all clear. But bleeding still continued. Was given ovaral pill but still bled.
Latest update was given norethisterone 5mg 4 times a day for 4 cycles. First two cycles were fine besides bleeding after intercourse on 3 incidences.
Now on end of third cycle and light bleeding has started. What should I do ? Continue nore or see obgyn.
