positive?

So I got on the depo in June. I am supposed to get it every three months (next one being 9/9-9/18) . Ever since I got it my boyfriend would cum in me every time we had sex . I would occasionally take a pregnancy test just to reassure myself.. So last week we had sex and he came in me for the last time bcus I'm not going on the shot again and I took a test a week later and this was the result .. Is that positive orrrr?? I feel like I see a very faint blue line but I'm not sure
