My obgyn told me to start taking the pills on the 3rd day of my period. But your taking it a week later. I don't think you should've skipped the placebo pills since you're taking birth control pills for your first time. Even if you could skip next months period why would you attempt to do it on your first month when you don't know what you're doing? I think your'e supposed to take a whole months of pills so your body can get used to it or something.
You took a huge chance by starting a week late and you took a huge chance skipping the placebo pills. Go ask your obgyn to find out what to do.
If you skip the placebo pills it skips the next month. But you are new at this so it might really mess a lot of things up.
