I’m freaking out!!!!! Is this a positive?

My husband and I have recently started trying, but it’s been somewhat a struggle. I decided to take a test on the first day of my missed period. I’m having slight cramps and it’s been 13 dpo. Do you all think this is a positive? The line was faint the first three minutes, but has gradually darken over time. I’m about to go get another pregnancy test just to confirm. I’m shocked/excited yet in denial.
