"i took ella 3 days after a little accident happened (14th and 17th feb 2017, respectively) and initially had no symptoms. however, my period was in total 18 days late. in those 18 days i panicked and really stressed myself out thinking that the pill might not have done its job and it may either be due to this or the pill itself that i experienced mild stomach cramps, nausea and fatigue. when my period finally came, it was lighter than usual."
