I dont eat or drink cold foods. Now, I'm not 100% sure if this really even helps but I have heard in the Western world this is what they do. Its supposed to help keep your uterus warm? I drink room temp. water and no shakes, ice cream etc. But I didn't follow this when I got pregnant with my 3 girls and I got pregnant right away. But since it's taking a lot longer this time i am willing try about anything.
I also stopped eating peanut butter and peanuts. Something about it depleting calcium levels thus reducing fertility. That one makes me sad!
