Clomid

Jessica
I will start my first round of clomid tomorrow. We have been TTC for 1 1/2 years now. I have a 3 year old already. I fairly regular with my cycles and have a period every month. I am just not ovulating. My doctor said it might be my weight and stress levels ( I am a full time education student/ mom/housewife). My question is should I wait to take the clomid and try to get healthier? I have lost 5 lbs in the last 3 weeks trying to diet and be more active. Will the clomid work better?
