I had unprotected sex maybe 3-5 days after my period. I then took the morning after till around two days after I had unprotected sex. About 6 days after I took the morning after pill I experienced spotting and now still am experiencing it two days later. I've read plenty of threads that say this is a common side effect, etc but I am worried because I've taken the morning after pill before (about a year ago) and I don't think I experienced any spotting. Today I've also experienced did one light headness and feel a but off but that could be down to stress. My actual period isn't due for another two weeks. Should I be worried?
