Are we positive? Can I be sure?🫣 Line eyes please..

9/10 dpo, depending on the app. I had a chemical pregnancy in august/September, so I’m very very hesitant to be optimistic about this.. Pic was taken at 4 mins with afternoon urine. Tested this morning as well, however the line was more faint so it seems to have darkened a bit. Thoughts? Advice?
