Help! New birth control - NO period.

Nivine
Hey guys! 
So I'm actually seriously concerned (I also worry a lot to begin with) but last month I was taking Micronor (mini pill) and it was my second month on them, I noticed about a week before I was "supposed" to get my period, that I was spotting/brown discharge and it worried. And then near the end of my pack (didn't finish), I started a whole new one Ortho Tricyclin Lo 28, I've been in these before & yes I am sexually actively with my bf! However, I've been having strange symptoms.... college student, and I'm too scared to take a pregnancy test :( is it possible... help
