Not spotting is a good thing! At the Early Pregnancy Unit today, they told me that spotting before you miss your period is considered normal but any spotting after you miss your period is classed as a potential cause for concern. However in many cases spotting does not necessarily mean a problem.
Gardenofedens - thanks for sharing your scan pic! I didn't get a photo but my scan looked pretty similar. What date is your next scan? Mine is 19th January. I love both of your names by the way!
