Is the pill effective the first time you use it. Example you use the pill (correctly) during the designated date the doctor required... is it safe to have sex after that? Or is there like an "incubation period?
As long as you follow instructions then it should be fine. As far as I can remember, you take your first pill the first day of your cycle right? You can have sex directly after this, so long as you dont miss taking them n.n
