What happens if you take your bc sunday before your cycle starts?

Question

I am trying to start my first bc pack early to get it in my system. Will I have a period if I start them early?

Answer 1

They tell you to wait, just so its less of an adjustment for your body to follow the schedule the pill sets.  If you start a pack in the middle of your cycle it could cause spotting and breakthrough bleeding, but it won't hurt anything and you might not have those side effects.
