I am 4 days late, and I am terrified of taking a pregnancy test :/ I am so worried that it will come up negative just like all the other times. But I just have a feeling that I am pregnant. I had a tiny bit of brown spotting (more like mucus) and then AF never came. I had diarrhea while I was spotting, and I have been extremely tired. I am just scared that this is all in my head and I'm imagining it all.
