After takeing an anti pregnancy pill it take how long time to start its action and how long its remain ?

If u take an anti pregnancy pill at morning can u njoy sex till night safely ? how many time u can njoy sex after taking an anti pregnancy pill ? is there ny restriction ?

are you referring to birth control or the morning after pill? Birth control takes about a month to take effect and as long as you take it at the same time everyday you should be fine. The morning after pill should be taken right after you have sex or the following morning to prevent from pregnancy occurring. The man's ejaculant can live inside you for up to 3 days! Meaning if you have unprotected sex Monday, you can end up pregnant on Wednesday!
