Hi! I'm taking diane35 for the first time start last sept.2 my first day of menstruation as my ob adviced. She told me to take 1 tab everyday at the same time if morning of 8:00am or evening of 8:00pm means i need to take it always same time everyday What if I take it evening but not always at the same time? And I missed to take it last night? It will not be effective I will get pregnant? Actually my husband arrival on sept.25 from abroad that's why I ask for my ob for protection as long as he is here, after taking those 21 tablets still protected on sept.25? Since, I took it not always in the exact time in the evening and I forgot to take it last nigt but my probably sexual intercourse will on my arrival of my husband on sept.25
