I was due on my AF on the 18/11 nothing has fully come only slight brown discharge smallest of amounts. Cramps every now and again. Peeing a hell of a lot and I feel like my boobs have grown I really want this to be true but I'm scared if I take a test it's going to be negative or I may come on tomorrow? I don't know what to do and I don't want to stress my self out! Did anyone else have this ?
