Dont know about the uterus sorry but maybe try temping? You could use the website fertilityfriend it will show you how to temp and all that jaz, all you'll need is a fertility thermometor (from the chemist, the normal ones dont work properly) and the website.

I guess you might need to do your research when it comes to what to and not to eat. There are some great sites, you might even find all you need on this website.

Cheers,
