I'm afraid I've been obsessing a bit. I started testing before AF was even due (like 5 days before) and got a clear negative on a Dollar Store HPT. The next day, nothing again, but when I looked at the test hours later, there was the faintest of faint lines but I figured it might be an evap. line. I tested the next day and again, faintest of faint lines showed up after many hours, but possibly a teensy bit darker. Finally on Saturday (1 day before AF was due), I got what I'd call a "squinter." Sunday, super-duper faint line - again after probably 20 minutes of waiting. On Monday, I got another faint line (1 day late) but it took between 12-15 minutes to show up. I think it was Tuesday or Wednesday (2-3 days late) before I finally got a line to show up within the 10 minute mark but still pretty faint. On Monday (1 day late) I used a FRER and it showed up within 3 minutes but not nearly as dark as the control. I took another FRER on Wednesday and just maybe it was a little more solid than Monday's FRER but again, not as dark as the control.
I took a Dollar Store test this morning with FMU and I guess around 3 minutes I could see where a line would show up (does that make sense?) Around 5 minutes, I could see a clear faint line with not much color. Definitely by 7 minutes, a clear, pink-purple line.
Has it been anyone's experience that the Dollar Store tests take a loooong time to fully develop? By 15 minutes or so, it was a nice fat pink line but still not nearly as dark as the control line.
It's always been my experience that I POAS and it's instantly as dark as the control line - at the same time the control line shows up. Maybe I waited longer to test before because I'd never ttc before? Or maybe I O'd late last month because my hormones were wonky from the m/c in Nov.? Or maybe it took longer to implant than most people (towards the 12 day end of the range?)
I guess I should take it as a good sign that the lines on the Dollar Store tests are now showing up within the time-frame and are darker than in the beginning but I sure would like to see a rapid, dark-as-the-control-line line. If my calculations are correct, I should be 4 weeks, 5 days today. Anybody else not getting super dark lines at this gestation?
