I've gone and got myself stressed this morning. So after my faint positive on a FRER yesterday, I later tried on a Cassnovum early result test, which have terrible reviews, but it was my last one of those so just used it anyway and got a faint positive on that too. This morning though, I used one my blue HCG strips that I got from Amazon, thought I could see a super super faint something, but looked more like an evap line, and after the 10 min window it's just the indents I can see. Are the blue strips just not very sensitive? Got myself all worked up thinking I got false positives or evap lines yesterday.
