I dont think its safe to try to loose weight during pregnancy- my GP said I could- but my OB just wants me to try to limit how much I put on- in almost 19 weeks I have put on only 3 kilos- although my body shape has changed dramatically. I'd lost nearly 20 kilos before I fell pregnant but put on 10 + of that before I got pregnant.
The important thing is to make sure you are eating healthy I think. Dont starve yourself or the baby. Its the nutrients that are important. While the baby can grow and be maintained on the mothers fat stores- it doesnt get all the nutrients that it does from food.

Ive never been a 'normal' weight- may have been classified as just overweight a few years back though- so I've never been treated as 'normal'. I'm used to not being able to find clothes that fit!

PS- i noticed some of you were in the newcastle area... none of you would happen to know where to get maternity bras from would you?? my only non underwire's are sports bras that have been stretched to within a cm of their lives!
