yeah i agree every pregnancy is different,my first i put on no weight i actually lost 10kg,my second i put on 14kg,my third i put on 33kg! and im now 12wks and ive already put on 8kg!!,and i havnt changed my eating at all.I was really worried as well but when i went to my first antenatal appointment the midwife didnt see a prob with my weight gain and said its prob fluid retention.So im just going with the flow
