Help?!!!

Lauren • Jacob💙 3 angel babies👼🏻🙈 pregnant with our rainbow baby🌈 19 years old - England💗

I was told 3 weeks ago now that I had a miscarriage but to do another test in 2 weeks time. I've just done a test and it's still coming back positive. The photos show the first pregnancy test I did (July - top test in photo) and the one I've just done (today - bottom test in photo). Anyone else had anything like this?
