preggers or nah

Hey y'all, so my boyfriend and I haven't been using condoms and he's finished inside of me like 3 times anyways I'm 3 weeks late, and I've been super nauseous for the past 2 weeks and I've been peeing almost every hour on the hour at night and pretty much during the day too. I know what you're all thinking I should take a pregnancy test, but I also know stress can delay a period too and I got a new job just around the time I missed my period. I really don't want to get my hopes up. Anyways please feel free to leave comments because as of right now the only person who knows I'm 3 weeks late is myself
