I have had no real symptoms at all other than a lack of appetite. I am having an early scan next week due to spotting for the past three days with dark brown dirty blood (only when I wipe, not on underwear etc). I have just eaten breakfast and am now feeling really queasy. I don't feel as though I am actually going to be sick, but it keeps washing over me, my mouth fills with saliva and it is noticeable. I didn't know whether some women have this rather than being physically sick? Could this be the start of it, or does it come in full force?
