One missed pill

So I usually take my pill every night at 10PM. October 14th I missed the pill that night but took the pill the next day at 10PM. So October 15th at 10PM I took two pills. I believe the next day or two days later, I started bleeding and it lasted until the end of that week. My period was supposed to start Sunday Oct 31st, but I haven’t gotten it at all. between that time and now me and my bf had unprotected sex, but he always pulls out. (Even before BC he pulled out and I never got pregnant). Every time after that, I have been taking my pill everyday on time. If you double up on the pill, will you miss your period when expected or what? Kind of stressing out, but then again I don’t think I’m pregnant. Please help. Thanks!
