emergency contraception
"Few days ago I shared my experience  after taking ella one, & was waiting for it to work. So I got my period  yesterday, on day 23 of my cycle. Which is a good  thing although  was really  painful-  I really suffered a lot of cramps after taking the pill. I think its better to use condoms  next time rather than  making any mistakes and regretting later on. This pill depends basically  on your period finishing date and the day you have unprotected  sex.."
