emergency contraception
"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."
