Hi . I am so worried right now because my menstruation hasnt come yet.. May i ask does the ECP is effective even though i ovulated a week ago ..cause i ovulated on the around at the 2nd week or 3rd week of september and i had unprotected sex on september 24 and 8hours after i took immediately the ECP. Is it effective or not??and to add up the trust pill contains 125mg of levonorgestrel . ..I am freakin worried about now ..
