[ozmidwifery] No weight gain @ 32 weeks?

[jesse/jayne]

I have a friend who is 32 weeks and since weighing herself 1 month before pregnancy, has actually lost 2kgs from that point until now.  Her doc doesn't weigh her and my friend had no concerns until others started to comment on her no gain at this point.  When she decided to conceive she was about 20kg over her ideal weight so she changed her diet for the better and began to walk 30 mins to 1 hour a day in preparation for pregnancy and she thinks this is why she hasn't gained weight.   This is her 2nd pregnancy.  1st pregnancy she gained 14kg but was 20kg less to begin with.   She has a nice big prego belly but is thinner around her bum/top of legs/arms than what she was before changing her diet. She looks great, had very little nausea in early pregnancy and baby looked fine at 20 week US.   We did some searches on lack of weight gain in pregnancy and now she is worried.   Seems all negative.  She is adament that she hasn't tried to keep her weight down purposely, only changed dietary/exercise habits for the better.   Should she be concerned?    Jayne
