This is my first pack of birth control pills and I started them right away when I got them. I ended up getting my period half way through the second week of active pills and my period ended 5 days into the third week of pills. I'm now going onto the placebo pills. Will I get my period again if I just had it? Also, if I don't get my period during the placebo pills will I be protected from pregnancy even though it's my first pack of birth control pills and won't be on my period this week?
