The fatigue kicked in between week 4 and 5 and my BB's were a little tender - nothing major but noticable. My MS (all day and night to be precise!) kicked in about half way through week 6. I haven't vomited but feel off most of the time, even when I get up for my middle-of-the-night loo trips. I've been feeling VERY pregnant since the nausea started - like I've been hit by a bus! I secretly love it though
