I'm 10 dpo. I've got clinical guard cheap ones from Amazon and I've got a store brand (Meijer) that's supposedly comparable to first response. I've read people on here talk about indents and possible false positives with different tests. So what's everybody using? I used my last store brand and the cheap one today. Store brand is possibly a vfl, though it's a blue dye, so I'm not sure if it's an indent. Couldn't really see anything with the cheap one. Hoping I can hit a store today to buy another test. I've heard good things about the Walmart 88 cent test, but we don't have one close to us, weird, I know. Haha.
