False positive?

[SN98]

So I took this test yesterday evening and this line came up straight away (9dpo) today I’m 10dpo and I took a test with FMU and straight up negative and I’ve taken 3 more tests today and all negative. All with same brand 😔 has anyone had positive then negative but we’re still pregnant?

Are these all different tests as they all have a line? If these are only the positive test, it could have unfortunately been evap line the first time if the rest are definitely negative now x

Yeah all same test and it came up straight away so I’m confused. I was only 9dpo when I took that test x

Sounds like it was an evap line then, I'd say potentially chemical but that's usually a few positives that don't tend to darken much. If you've only had the one positive it's likely it was an evap, they happen alot unfortunately. Tho you are not out until your period shows so still hope x
