Quoting ☮ Phuket:" thanks, looking at the last 2 frer i took IRL they looked very close in color. just wanted another set of eyes"
I took two of the FRER tests and the lines were much darker than the dollar store tests that I took. The line on the dollar store tests were barely even noticeable. I think it's pretty safe to say that your lines are getting darker especially since I experienced the same thing with the same tests as you!
And if I'm correct, I'm due around July 25th. Due date buddies!
