My period was due yesterday, and I took a test today- this morning it was negative and when I looked at it later- there was what I thought, a evap line. I took a test tonight- and I thought I saw a line, but I have been driving myself crazy- about ten minutes later I looked at the test again..... and there was a faint line- but could it be another evap line?! Or is this my rainbow baby after three losses?
