mine started at 6 weeks but not actaully been sick yet. I had one or two flutters of sickness beofre that on odd days but nothing major, now im praying for it to go asap, as it's 24/7 my midwife said that as i havent been sick yet it's likely to fade away by week 12, here's hoping! you dont want it, it does reassure you that your hormones are raging but it's really not nice and my love goes out to all you spewers, it msut be horrid! No doubt ill get it worse next time, (im already hoping for a next time LOL!)
