If you read the packaging that came with the test, itll tell you to read it after like 1 minute but not after 10 min or something like that (each one is different and has different times). If the line showed up when you first took it, id say it means pregnant, especially since the other 2 said pregnant. You can always take another test just to be sure though. :)
If you took two other test your pregnant. I took one test said pregnant took another one a hr later n the results had faded lines. I'm pregnant
I think I took over 5 different test till I actually went to the doctor and saw the baby on ultrasound I'm still shocked lol but I'm now 19 weeks lol
