I felt a little nauseous between 4-5 weeks on and off. From 5.5 weeks (last week) it kicked up a gear and today (6weeks) it's pretty bad. Everything smells rotten, can't think of anything to eat and I puked this morning. I do know though wi all previous pregnancies I would get an odd relief day here and there where my symptoms dramatically faded - say around the 8 week mark- though instead of being grateful I would panic worrying about the pregnancy. Symptoms would be back with a vengeance a day later and I always swore next time I would appreciate my "mercy" day. ( but no, next time it happened I would worry all over again !)
