Stopping the pill. when will I get my period?

So I had been on the combination pill Aubra for 6 months. It was great to me by the way for the most part. However, I decided my body needed a break, me and my boyfriend were too busy with work and college anyways that we barley even had sex and when we did I made him use a condom and pull out. So in all honesty I didn't feel them necessary anymore. I took my last active pill on Oct. 22nd had my regular period on my sugar pills and have since then been off the pills. I have gotten a few headaches here and there since being off but other than that I feel as normal as ever . I recently had sex with my boyfriend a few days ago , we used a condom and he pulled out so I'm not really worried but is there a time frame in which I should get my period after stopping the pill? I don't want to be anxious for long lol. My periods were irregular before the pill. 🙁
