HEllo .. I had my period the 13th of Dec - 17 Jan. Had sex the 18th and took the morning after the next morning, the 19th. Had sex a week later and got the morning pill the next day again, that was the Monday Morning the 23rd. Had sex the night and did not drink the pill again as i was feeling sick. Had my period,or more like spotting for two days now. nothing today though, i am tired and lower back pain and terrible mood swings. please some advise will help? is it because of the morning after?
