I'm 36 weeks on tuesday. Managed to only gain a couple of pounds through this whole pregnancy, infact i even lost some. I have just gone and got on the scales and it says i am 8lb heavier than i was 3 weeks ago. I do have swollen ankles and feet so could it be fluid retention? Noticed i am not weeing as much as i was today although it is very hot and i am drinking a lot. Anyone else?
