HELP! Stopped BC...

At the end of my last pack of BC...I had my normal withdrawal bleeding and didn't start a new pack. The last pill I took was Oct 13. Since my withdrawal bleeding, I haven't had anything. I have had some signs and symptoms of what seems like PMS, but no AF! How long until I will see anything? My husband and I recently got married and are TTC (well want to start). I'm nervous!!
