I don't diet, but I do try to eat clean. I would say I probably take in about 1700 kcal/day (I'm 4'11" 95 pounds) and it's well balanced.
I charted with #1, but my husband asked me not to for a few months just to see what happens. I had EWCM on CD 10, so that gave me hope

I do think that my body naturally functions just fine with a low body fat. I was an high level competitive gymnast, so that is kind of how I grew up.
I just get worried. TTC can be so stressful!
