"i took ella one 42 hours after having unprotected sex with my boyfriend, and have heard ella is still very effective,  i have also took levonile before around 6 months before this mishap and everything was fine with that no nasty side effects in fact none at all, but ella one is a different story, i have felt very ill for about a week of taking it! day one after taking it i started bleeding which lasted for only four days this wasn&#039;t a problem, but the pill has made me feel so weak still do this day my whole body aches i have had constant severe floods of nausea and i&#039;m constantly tired and my belly has been cramping as hell, i do regret taking the pill after the way i feel, and wish i got levonelle on the time frame needed."
