I've been trying to conceive since may...I took a test last night and this morning and both had a very faint line but I took another one ( ClearBlue Digital) on my lunch break and it said not pregnant. I don't understand..! I'm literally almost a Month Late. Any body have any answers as to why I had a positive in the morning and a negative digital?
