I started my period on 12-23-11 and by Monday 12=26-11 had finished or stopped bleeding. Normally I bleed for 5 to 7 days. Well on weds 12-28-11 I had unprotected sex and within 4 hours I took the first of two morning after pills. 12 hours later took the sercond morning after oill as instructions stated. Now today being 1-1-12 at 7:30 pm had an all of a sudden discharge of blood as if starting my period and now 5 hours later have not bleed anymore. What should I do? What could this be? Should I go to the hospital or what?
