What are the signs you are pregnant?

Obviously I know what the major signs are. My periods are regular as are my moods and my emotions and everything else in between. What I'm wondering though is, if I've caught on being pregnant in the early stages, would I still produce mucus down below, do I still get a dull ache at the time of ovulation? Do I still feel emotional when i normally would?!  Obviously I've never been pregnant before but it would be nice knowing what to expect when your are first expecting.
