Hi,
Welcome to ehealthforum,
The migraine headaches can get aggravated by use of combined hormonal pills. If you wish to delay your periods, you should consider visiting your doctor/gynecologist for getting prescription of pills for postponement of periods. Norethisterone can also aggravate migraine attack (frequency and severity). Discuss with your doctor/gynecologist about safer options, and avoid self medication. Cerazette is usually prescribed to women with migraine as it is newer and safer pill that reduces incidence. You should consider visiting your doctor/gynecologist if you develop symptoms suggestive of side effects.
Take care.
