What is a healthy BMI to be at when TTC?

Just wondering if anybody in this group has researched what is a good BMI to shoot for when TTC?

Nothing I have read will actually say what your bmi should be, just that it is harder to get pregnant if your bmi is above 30 or below 20. So just somewhere in between there. Hope this helps.

I know for me personally it is a BMI of 22.  That is what I have read for my height 5'2''.  I am working my way there. I am at 23 now! Yay.
