Could be an evap line if it has been sitting for a while. That's why instructions say to discard after so many minutes. Evap lines can appear and make it look positive when it's not.
I don't know how/why there's a faint line on the cheap one
I just took a first response one and it was negative :/
The doller store tests didn't show up untill the next day for me when I was that early. I would say there's a good chance your pregnant. I would either buy another test or take the dollar store test again in 3 or 4 days.
I'm not sure if your asking about just the test or also having another child this soon? But in my opinion it depends on you I know alot of women who are fine with having kids back to back and others who don't or feel they can handle it. I don't have experience with having kids back to back this is my first pregnancy. I've seen a few post on here about women who do have kids back to back hopefully one of the experienced mommas on here can help
I have been told you can't have a false positive only a false negative. I believe there might be a possible way to have a false positive depending on medications someone might take not 100% though. But from my understanding you can't have a false positive. My home pregnancy test was a faint positive as well it was the store brand so I thought maybe I did it wrong too or checked too soon when I told my partner about the results he also said it can't be a false positive he is a chemical engineer and worked with feminine products for a while so he knew a thing or two when it came to pregnancy test.
