Any picky eaters have trouble getting pregnant?

I'm an extremely picky eater, and part of me wonders if I'm having trouble getting pregnant because my body isn't getting the proper nutrients. I've been tested and so has my husband and everything looks good from what they can see! I'm SUPER picky. I hate all veggies, except corn and potatoes and those are just starches anyways. Hate all fruits but apples. The list goes on and on! I take prenatals and vitamin C for my immune system.

Just wondering if anyone has heard FROM A DOCTOR ( not Google) if this could be a cause? Thank you!!
