Pregnant on the pill?

So I recently start the pill only to stop my period whilst on vacation, I didn't start taking it on my first day of af as I wasn't using it for protection, I've been on it for two months and not had af. Recently I've been very sick and constantly tired! I've also notice that my breast have become bigger and veiny. We decided to stop trying so hard and just let it happen when it's happens.
