Trying to figure out if I should take another pregnancy test, & if so, when?

Little back story on me:

I've always had VERY heavy periods since 8th grade, finally went on BC in high school to help regulate it & literally have NEVER missed a period; even though I was very skinny in HS, active in sports, stress, etc.

My cycle is typically on the shorter end (27-28 days). I'm currently almost on day 32 (4days late) so I took a test this morning & got a negative. I know they suggest waiting a week after missed period to test, so I'm trying to decide if I should try again in a couple days, just wait for a week (or more) after, or if because I am late and got a negative should I trust that I am probably not pregnant?

Suggestions?
