My morning sickness started early week six and then I had a 'few days off' - where the worst I felt was a bit 'ick'. But yesterday it came back in force! It started about midday and then I couldn't keep my dinner down last night, and then this morning I vomited again before breakfast (my tum didn't like the bit of water I drank). So I guess it comes and goes as it pleases. The bit I'm not liking though is the constipation!
