Implantation bleeding or early period? HELP

Hello, I am currently freaking out because my boyfriend and I are trying to avoid pregnancy but this happened. We had protected (used a condom) sex three times during my ovulating period. (I understand I have a higher risk of pregnancy, but when youre in the moment.. you probably understand) My period is supposed to start in exactly a week from today. However this happened... I was in the restroom and when I went to wipe, I saw blood on the paper. I was confused because my period isn’t supposed to start for another week. So I researched... and well implantation bleeding came up numerous times. I found out implantation bleeding occurs about a week after ovulation. Does the blood in the pics seem like implantation bleeding? I plan on taking a pregnancy test tomorrow. I’m cramping really bad, similar to my menstrual cramps. After putting on a pad, I went to check again in a few hours to see if it was my period. But came to find what you see in the second picture. Dried blood. However, when I wiped, it is what you see in the first picture.

I really need advice. My boyfriend and I are fully supportive of each other. We both do not intend on having a child this early ( we are only 18)

Please help. Thank you so much.
