From what I've been told, it obviously takes a month or so for your body to adjust to the hormones and my doctor told me to still use protection for about a month on the pill because it isn't completely in my system and protecting me from pregnancy yet. So the placebo pills. They don't have any medication in them right? After I've been on these pills for at least a month am I protected from pregnancy while taking these placebo pills for a week, being that there isn't any medication in them? I need to know when I can have sex and when I can't. I know there's never a 100% chance that I won't become pregnant, but I need to know if I'm protected every week of my card or just the 3 active weeks and I need to refrain from having sex that last week.
