I took postinor2 in October and got my period 6 days later as at when due. It lasted for 6 days. Took postinor2 again in November on the 14th day of my cycle (though there was no ejaculation). Got period 2 days earlier than it should be, lasted for 6 days with some spotting before and after period. Expecting my period this month tomorrow. Noticed egg white cm around 13-21 days of my cycle instead of 8-16. Could postinor2 affect my menstruation?
