I don't feel especially unwell but have had significant bouts of both this morning - haven't eaten anything dodgy (I don't think) and didn't feel unwell when I went to bed last night (although I did feel sick when I got home from work yesterday afternoon).
Just a bit panicky as I've read somewhere that some labours start in this way and am a little on edge as several of the women in my ante natal class have had theirs early ....
