When i was trying for my first child, 14 yrs ago, I was put on clomiphene for 6 yrs, I asked on my first consultation can weight affect my chances of falling pregnant and i was told no. 6 yrs into the clomid I read an article in a mag in a doctors surgury that said if taken for more than 6 months it becomes counter productive...hinders rather than helps, I also read that fat cells hold oestrogen..think it was that one, and the more fat cells you have the more of that hormone is present. From that day i stopped taking clomid, I calorie counted like my life depended on it and lost 3 stone within 6months, by the end of that 6 months i had concieved. I conclude now that maybe losing the weight which I was told shouldn't effect my chances of having a child, reduced my pcos symptoms enough for me to concieve on my own
