Hello ladies

I am overweight at 198 pounds and I am 5 ft 7in tall. I have regular cycles 27-29 days long monthly. I been trying for 10 months after a miscarriage earlier this yr. Now I will be going to a reproductive endocrinologist. I am expecting him to comment on my weight. If I am over bmi of 25 and have normal cycles (and ovulate every month also), weight could still be contributing? I have read articles that says regardless of a regular cycle, being over a bmi of 25 messes up ur fertility
