I'm 11dpo and decided to POAS for giggles using a first response. Within the 3 minute window a very, very light pink line showed up. The camera doesn't capture it well, so I inverted it and it's still a squinter. I showed it to my husband though and he saw it too. I don't want to believe it yet, because I don't want to get my hopes up. Do you guys see it?
EDIT: I just noticed the picture when uploaded doesn't really show anything. There is definitely a line in person though, but my camera sucks.
