Should I test?

I’m currently 5 days late for my period. My last period (Jan29-Feb2) I only spotted the first day and the other 4 days, I had nothing but brown discharge. It also started 3 days after the app showed my period starting. I’ve been off birth control for a little over 3 months now and wonder if the changes are imbalances caused by quitting the BC or if I’m actually pregnant. I would just hate to test too early and get another negative.
