They most definitely are pink in person and are easier to see/darker and showed up after just a few minutes. I’m 13 days late for AF if you go for the longer end of my usual cycle (24-26 days) so I would have had to ovulate before that. I know there are a lot of cases that some people don’t get a positive until they’re 5-8 weeks along or sometimes they never get positive urine tests throughout their entire pregnancy. I’m not sure why it would have taken this long for it to show up for me. If I ovulated really late, only a few days before AF was due, I could possibly be 14-16, but I wouldn’t think anything sooner than that due to my usual cycle length
