Negative ?

I took a pregnancy test 5 days before my period and it was very faint. Then 3 days. Still faint but darker then 2 and 1 days before and negative. (I switched to a pink dye test for those two test and the rest were blue dye.) I’m now 6 days late. Still negative. Having some signs of pregnancy. I’m not sure what to think or do. Has anyone else been in this situation?

Edited to add:

I’m not having spotting that looks like implantation bleeding.
