Am I pregnant ?

Claudia

Hi I'm 17 I just started my 3rd month on birth control and my second month period didn't come with blood it was just brown discharge lasted 2 days and that's the time I was supposed to get my period I saw blood when I would wipe but not on the pad or anything it wasn't a lot . I'm currently on the pill tarina fe I was wondering if this is normal or if I should take a test .
