She doesn't like Him(crested)

I know everyone says breeding crested geckos is easy, but I can't seem to do it. I have read books upon books and hundreds of forums, and I can't get them to breed. Right now I have my female who is about 30grams(i know its alittle small, but its ok for her first clutch) and a male who is about the same. I got both at the pet store so I had my male since january 2006 and the female since about may 2006. They are between a temp of 75-79 degrees most of the time and are being misted extra. I have a lay box in their filled with moist peatmoss, and I am feeding them CGD with a calcium suppliment. Before this their average temp for about a week to 2 weeks was 69-73, but varied greatly due to weird weather. I catch my male trying to breed with her(licking her and chirping) but then she shakes her head rapidly and makes another type of chirp and he stops. Any thing extra I could do to set the mood? and if she is pregnant how can i tell? I know you can feel the eggs, and i have been checking but when I do on somedays it feels like their are 2 eggs in their and others if feels empty. Any advice would be greatly appreciated very much! Thanks in advance

You don't need to supplement her with any calcium. CGD already has more than enough and too much supplementation can harm them.

I gave well below what the bottle said, i didn't think CGD had enough in it for a pregnant female. Thanks though, and good news.
This morning I found 2 bouncing baby eggs :P

calcium intake for a breeding female is very very important. Females use calcuim to make the eggs, so they need more than males. CGD isnt enough. Check out pangeareptile.com, they offer a calcuim that is made for Breeding females and growing babies. Isnt much i think its 7 buks. I dust my crickets and add to food. Good luck
