Has anyone gotten a BFP super faint line (Equate brand) just 5 dpo?

I took an Equate pregnancy test and got a super super faint line right away. Then I took another the next morning and got a negative. I have been having lots of symptoms for a few days now and I know its not in my head because I'm so in tuned with my body. Now confused by these tests. Any input is much appreciated. Thanks!
