Please help. Am I pregnant ?

Hi. Some of this might be tmi but I am now 5 days late on my period. I usually get pms symptoms like my breast hurt, or I’ll have strong cramps however, I’ve only had slight cramping. And slight dizziness. Yesterday I took a HPT and it came out with a horizontal line in the test box. I attached a photo.

Last night, when I used the restroom, I saw some spotting on the toilet paper. (I attached it too. I’m sorry. I’m just going crazy wondering). I was wondering if that was implantation bleeding.

However, today I took a dollar tree HPT and it said negative. Could I be pregnant ? Should I wait a few more days before I test again?
