eating struggles

Lucy.
Currently 14w6 - and still suffering when it comes to food. Seem to have become vegetarian and am really struggling to find any foods I fancy/enjoy. Every meal time is a pain. Have to eat because if I don't I feel sick! Struggled really bad with nausea in first 12 weeks and although that's eased food is still a problem. Can anyone else relate?? First pregnancy with twins... also freezing cold all the time?! Seems so odd! Anyone in the same boat?!
