Faint line...??

I took this test weeks ago but think it's my eyes playing up, so don't know if there's a faint line actually there. I've previously been pregnant but miscarried and I took 10 digital clear blues and it was only the last one that came back possitive and I was 6weeks 3days so my HCG levels are not the best. Opinions Woc be appreciated. Thanks in advance 😊
