3 days before period

Isabella

So I have no symptoms of my period about to start and the only symptom I had of pregnancy is I threw up once and I had pink blood on toilet paper 5 days before my period it is now 3 days before my period and I swear I see a super faint line on a first response test but my digital was negative. Am I going crazy or will this be my month? Been trying for a year and 4 months now.
