Pregnancy

I took 5 pregnancy tests from a box I got from amazon that has ovulation and pregnancy test strips. The first test looked negative but if you looked a certain way it was an extremely faint line. The second was a faint line but noticeable. The third I took that afternoon and the same thing as the morning another faint line. And then today I took another one and it was more noticeable, my camera is finally picking it up but still faint because I’m not due for my period for another 5-7 days. I started taking the tests from 7-10 dpo. This is the first time I’m getting consistent positives and my mind is sort of in doubt. Does this mean I’m certainly pregnant or there’s a chance I’m not? It’s the iProven test strips
