When I went to get the blood test I was about 3 weeks and weighed 121 lbs. I'm now 6 weeks and 2 days and I weigh 117 lbs. I just started getting morning sickness yesterday but it was just nausea, no actual sickness. And I have been watching my weight drop slowly everyday, so I know morning sickness can't be the cause. I eat pretty regularly I think, so that's not the cause either. So I guess I'm asking if anyone else is experiencing this and if I should be worried? Any advice is welcome..
