I'm starting to think that I have wasted a ton of money buying first response tests. Today I am 11dpo. I tested with fmu on a First Response and got a faint line. I decided I wanted to check my line progression so I bought more tests at the dollar store just to see if it would show up on them yet and to my surprise it did!!! And these tests are only 1.00. Also the line looks about the same darkness in both tests!!!! I could have been buying these all along instead. Please tell me what you guys think? Have we been wasting our money?
