I have done cd before and lost couple of stones before wedding. I am currently ttc and have lost couple of stone through calorie counting and excercise. I have been stuck at same weight for weeks and need to lose around 9lbs in just over 3 weeks. Concerned about cambridge in case it stops me ovulating but really need to get my weight down so I can be refered for treatment. Does anyone see any problem with me doing cd for 4 - 6 weeks for a quick boost and then reverting back to calorie counting and excersise after that.
