Is it normal to lose weight during pregnancy?

I have lost 2 kilos in less than a week due to not feeling well,
should I call my midwife in the morning or is this normal especially if I have nausea/vomiting im not that hungry anymore,

im drinking my water but only eating cause I know I have to...

cause of baby but im feeling weak when I do eat it just goes straight through me,

has anyone ever experienced this?

I was lucky enough to not have morning sickness at all when I was pregnant. Have you tried saltines to help with the nausea? Ginger Ale also seems to help some people as well-ginger is good for nausea.
you might try several small meals over the day, instead of 3 big meals. Don't put too much in too fast. your prob weak from the vomiting and from not eating as well.

2kg is between 4 to 5 # here, I think you should prob give her a call. That's a fair amt to lose in one week.
Luckily, in most people morning sickness ends around the beginning of the 2nd trimester, so there is a light at the end of the tunnel. (=

If I were you I would get professional help on this one. if your not feeling well and not keeping food down your child is losing its nutrition to.; which could be very dangerous...Good Luck
