I have been super tired and having headaches, and having sore nipples. I took a test Wednesday, and got a bfn. I came home today after work and my boobs were sore so I decided to test again. Again, a bfn.... or so I thought. I was cleaning the trash up and noticed a very faint light pink line. I grabbed my test from Wednesday and no line on that one, so I don't know if it means it's positive or if one just got a evaporation line and one didn't? I'm really confused!
