I've been using Promatris tests but didn't read any reviews. Where a positive should be I've got nothing or a faint shiny clear line. I decided to read reviews and most reviews said they got negative with every one of these sticks they used but positives on branded ones. Another review said she got clear shiny lines and bought a first response that was positive! Aopparently these sticks are useless until 26dpo. So tomorrow I'm running to the shop as soon as I'm up for first response tests!! Ah I'm excited. Probably get a bfn but it's so nice to have a bit of hope again.
