First response test help

[Strawbs20]

Can anyone help please, I picked these up by mistake, was meant to get the early result ones. When can you actually use these tests is it day of suspected period or once its late? Thanks so much in advance

It should say in the instructions how and when best to use them?

Double check the info sheet- most will say in more detail how accurate they are before your missed period. You can use them at any point but they will be more accurate the closer to a missed period or after you've missed one.

If you use them early and get a negative just be mindful it might be a false negative, but if you get a clear positive then it's positive x

I believe rapid response are 25miu where and they recommend testing the day of missed period where as early response are 6.3miu and you can test 6 days early

Thank you for your replies 😊 much appreciated xx
