I don't think the lines are darker today on the Wondfos- they they are dark lines and much darker than two days ago.
My FRER is actually much better today. It is possible that my wondfos are starting to max out. I've found that they increase slowly after a certain point. It is also one of the old style, flat FRERs. I have heard from several early testers that they are less accurate in early testing than they used to be.
Anyway, yesterday I held it from 1 to about 5:30 so I could use a digital. I wanted a way to estimate it my HCG was scary low (I've seen women take a wondfo with a faint positive and have a beta under 10- which would be very bad news for me at this point). Digitals are notorious for needing at least 25 and more like 50 to show positive:
And it was positive! It didn't take too long to come up either!
About 3 days and 2 hours until we get beta results.
