Pregnancy scare

So i am currently 13 days late... yes I've taken a pregnancy test actually at this point I've taken 3 to be completely honest. They all came up negative. ThANK GOD. But im still late. Also i had spotting for a couple days right around my period which i was told come have been inplantation bleeding ? But it wasnt really the right color. I have also been wondering if the spotting could have been like a super light period due to the uti i had previously which i heard could affect your period. I have no ides whats going on just let me know what you think or if you have experienced this what it was.
