Hi are these positive or am I crazy

[KRichards97]

Hi I recently took quite a lot of tests the ones below are confusing me but I have had very straight negatives in between these, I'm about 7 days late on my period .

Any advice would be great

Definitely positive :)

Congratulations:)

Second one is faulty 1st and last positive

This

But I’d be expecting much clearer lines for 7 days late. It may be a chemical. Your doctor can test your hCG levels.
