So I am 4 weeks, 1 day and I have been testing since I found out since I have the extra tests.  The lines on the cheap tests appear to be getting darker (I take these daily) however the first response actually seems lighter today than it did Tuesday.  Do you think that's a bad sign even though the other tests show the line getting darker?  This is my first pregnancy and I'm so nervous I'm going to miscarry!  Thanks!
