Pregnant?

Okkay so me and my boyfriend aren't really trying but I'm really bad at remembering to take my bitch control so whatever happens happens. I had some spotting almost 2 weeks ago so we were gonna wait for my period to see if it was anything. my period was supposed to come yesterday but didn't and I took at test 2 days ago and it was negative. should I test again? Or just keep waiting for something to happen?
