Cycle Day 7

I lost a dramatic amount of weight when I went gluten free- around 30 lbs. Then when we moved about a month ago, we got a new fabulous stove, I started baking. A ton.
I make cookies about every other day. I don't eat that many, I don't think, and they are gluten/wheat free. But I think I've gained back 5 lbs this month and this isn't a good thing.
My mother has gotten on the fertility bandwagon. Before this last cycle she was always saying things like, 'it takes regular people many months to get pregnant'. But then she talked to other people, and has seen it on TV, so it's become a real issue, my infertility.
She called last night to tell me about a fertility diet, which was sweet, (I already am eating for fertility- mostly), but she got me freaked out about my cookie eating.
Okay, so we NEVER go out to eat (I can't because of celiac), I NEVER eat fast food, I NEVER drink soda (except every 3-4 months I'll have a natural soda from Whole Foods) I NEVER have direct caffeine, I NEVER drink Coffee, I NEVER consume any alcohol, I NEVER smoke, I NEVER eat processed foods.
I think I'm okay, and my RE said there isn't much more I could do, except keep up with the exercise. They all said I don't have that kind of direct control.
So why do I feel panicked like there is something I'm missing, that if I do, I will get preggo?
