False positive test?

[Wanttohelpbuthow]

My period is 3 days late according the flo app so I’ve just taken a test. I had a few left in a bag of cheapies from Amazon. I took one and it immediately looked strange as the dye was only going along one half of the test at a strange angle. This then eventually evened out and showed a positive.

i took another as I thought the first test looked so odd to start with (using the same wee from a pot) and this came back negative.

everything I’ve read online seems to say false positives don’t happen but surely in this case it is? I took them minutes apart with the same wee sample.

Personally I wouldn't take that first one as a positive, especially as it was followed by a negative.

Test again first thing tomorrow morning and see what the test looks like.

False positives are usually evap’s/faulty tests and really are quite common, I wouldn’t say that is a genuine positive
