Positive test only at night

[Leigh111]

When I take pregnancy test with first wee of the day it's negative. However when I take one in the evening I get positives like this. Anyone know why?

Could you just be really early? If so it could just be that your evening wee is more concentrated

You could be further on than you think, the hook effect is actually a thing.
you will only get a positive with more diluted urine (which in your case is evening) which would make sense. In the morning get some pee in a cup and water it down and test, if it show’s positive I would say it’s most likely the hook effect but do ask for a blood test to confirm. In very very rare cases blood tests have shown negative but the person has still been positive. Sounds crazy but it is real.
