morning-after pill safety? Does it disort the cycle?

Hi,
Welcome to ehealthforum,
Since the emergency contraceptive pills contain high dosages of hormones, these affect the hormonal and period pattern causing delay in next periods. Repeated use can affect your menstrual cycles severely causing disruption of your hormonal pattern and period irregularities, ovarian suppression, uterine or endometrial problems, etc. Wait and watch for your periods which could be delayed due to the emergency contraceptive use. Visit your doctor/gynecologist for further evaluation if periods do not start within 10 days or if you suspect chances of pregnancy, or if you develop any other new symptoms. If pregnancy gets ruled out, and if you are not ready for pregnancy, but intend to remain sexually active, you should consider visiting your gynecologist to get started on suitable regular birth control measures to be protected (after your periods). Be regular with birth control use as instructed. Avoid having unprotected sexual contact if you are not ready for pregnancy, and avoid repeated use of ECP.
Take care.
