Positive in the morning, negative that afternoon???

[GreenMum24]

Hello,
I took two Clear Blue tests, this morning and last night, both positive, one digital, and one line.

This afternoon I took another two tests and they were negative.

Is this common in early pregnancy?

Many thanks.

Very common, first pee in the morning is less diluted, that’s why they say to test in the morning.

Hormone concentration varies with hydration.
I would stop testing so frequently you will add to your stresses rather relieve them. If you do want to keep testing, keep to mornings, just once and every couple of days. Your HCG should double every 2 days. Tests don't tell you about the health of the pregnancy just that you are pregnant.

Yes it sounds like you're just testing very early and FMU tends to be the most concentrated.
There's no point in repeated testing, better to wait a few days between each test

Is this a positive?
