Gravid Snake not Laying Eggs

For the past couple months, I have been attempting to breed my two corn snakes, both of which have never been bred before. I have a candy-cane, part albino male and a beautiful Miami female, who is about 3 years old. I successfully brought them through brumation and saw them have intercourse (photo included) about a month ago, after which I put the female back in her terrarium (They mated in the male's). Three weeks ago, the female shed, so I introduced a lay hide to her terrarium, a wooden one with moss. I spray the moss every couple of days so it stays moist, and changed out the female's large water bowl for a smaller one. However, though the female has spent a lot of time in the lay hide, I haven't noticed a significant bump near her tail, which makes me wonder if she is even gravid. It has been nearly three weeks since the post-intercourse shed, and she still shows no signs of a bump and has not laid any eggs. Should I be worried? Is it possible that she isn't even gravid? Photos of intercourse and of the female are included.

She doesn't look particularly gravid. But you should probably have her examined by a vet to be certain nothing is wrong. I lost a girl to eggbinding this year, it sucks.
Also, your male is a standard amel, not a candycane.

You mentioned that they mated about a month ago and the female shed about 3 weeks ago.
Another possibility......With some young 3 year olds, they may go through a second post burmation shed before ovulation. I would pair them up again and wait for another shed cycle.
My corns lay anywhere from 6 to 10 days after pre-egg laying shed. No eggs after 2 weeks may mean a problem as Megan mentioned or she may have re-Absorbed her eggs.
I had a 4 year old corn mate and had obvious signs of ovulation but never layed eggs that year. However this same snake layed eggs the year before and after the re-absorbtion year.
Her 4th and 5th years she had the same mate with obviously different success.
Keep us posted.
