Not all tests after 5mins are invalid!!

Georgia

I have noticed a lot of people saying if a test has 2 lines after 5 mins it is invalid. Not always the case. When I took my tests, they all took at least 15 minutes for the 2nd faint line to show. I am now 11 weeks pregnant. I'm not saying all tests are valid after 5 minutes but for some, it takea that little while longer for the 2nd line to appear!

Baby dust to you all x
