i saw this link, i think better dont think too much, more stress. just do whatever you are comfy with. there are girls out there, super unhealthy, drink beer and smoke also can get pregnant not once but twice etc. so i think sometimes the more we worry the more we avoid we may face with more challenges and disappointment.
but of cause it can be a guide to you at least you know what to eat best for yourself. anyway my doc say cold drinks is ok, dont know good advice or what, everytime i see him he just is so positive, smiling and assuring really nothing wrong with cold drinks. so i also dont know what to do. he gave me permission for shopping and eat whatever i like after egg transfer while my tcm say bed rest next few days and no cold drinks and avoid cold food. lol. so for me, i hear abit here and hear abit there, of cause favour the one i prefer the most hehehe. but i do stop my cold drink intake for now. maybe till BT! i am still walking around and working since transfer date, so hope nothing will go wrong.
