I asked him about my being overweight (70 pounds!) and if that may have been a contributing factor to my delay in getting pregnant.
He said that all the research shows that being overweight only affects fertility when it's connected to insulin resistance, which shuts down the ovaries and keeps you from ovulating.
Sooooo.... if any of you are a little fluffier than is ideal, like I am, and were worrying about that as a possible concern (like I was), then you can know that if you are definitely ovulating-- per your chart, OPKs, etc.-- your weight is not a factor.
And you can eat a cupcake or run a marathon or whatever you feel like doing.
If you're not ovulating, then you can ask your doc about testing you for insulin resistance (H1AC)...
