HELP! am i pregnant

so my bc got all messed up because i got my period a week before the sugar pills and then I was still on my period a little the week of the sugar pills. and then i didn’t have bc for 2 weeks after that cause my pharmacy wouldn’t send it over to a new CVS anyway so i went home from college to see my bf and we did it and he used a condom and we always do anyway but i wasn’t in bc at the time and that was like 5 weeks ago and i started my new pack of birth control 3 weeks ago but i haven’t had a period since the 8th of november… and now i’m very worried i could be pregnant.
