i am very overweight and have recently lost a bit of weight which while great isn enough, iv just got my BFP today. im now seriously concerened i should have made more of an effort to diet before. now i love swimming and am going to up this to 3-4 times a week because its not load bearing, and also try and walk more is there a set number of calories i should follow to ensure its healthy without being too little food for baby? as i know i should try not to "diet" as such but eat healthily instead, or do you know differently can ii diet within a healthy range and still ensure my baby gets enough nutrients? i dont want to make any more complications than is nessacery for me or the baby during preganncy im 15st11 now and im only 5ft5 so this gives me a very high bmi though my wieght is around my bum and legs and arms more than my stomach and chest (ie im pear shaped rather than apple?) ( i was overweight last pregnancy 15st1 and went up to 16st 7 at worst after eating rubbihs as a coping mechanism after lost last one unrelated to weight i realise now that really didnt help for this time) any ideas and help would be great i never drank much alcohol before anyway (i drive trains and cant drink often for my job) so cutting that out is no problem. i dont smoke either and never have done. i am partial to eating rubbish and snacking, and i am lazy and dont do enough excersise. help apprichiated.
