One of my very first questions is - how old is she? I don't think they should be mated till they are 9 months old or so? I'm not sure as I have a smaller breed that can be bred at a younger age.
I have usually found that when a doe cries at mating - (for my does) -they're usuallhy pregnant already - or just not quite ready.
What I have started doing over the last couple of breeding sessions - is to wait until my doe is READY to mate...then it goes so easy.
So how do I know if my doe is ready to mate? She chins everything...water bottle, cage, food bowl, etc. They chin it excessively. They lay with their back legs in such a way that they're vent is almost exposed - as if it is uncomfortable for them to lay like they usually do. Sometimes they will "grunt" at me when I go to feed them - I've often found that a doe that is ready to mate is more talkative and grumpy.
You have a couple of options with the situation you have right now. Count 31 days from when you tried to breed her and just wait until then. I have a hard time palpating unless the doe has had several litters already....otherwise - I'm still too new at it to really get it right.
You could try to rebreed her. I'm not sure I'd do that if you already bred her. Is there a chance though that she was already bred before you got her? How long have you had her?
Those are just a few thoughts...
I do have one other suggestion. Join the National Flemish Giant's Breeder's club..no..I'm not a member but I'm betting the guidebook you get might be a good reference..

According to the membership application here:
http://www.nffgrb.com/MembershipApplication.htm
It has a 200 page guidebook as part of the package...
For a single member it is $10 per year - for a couple it is $15 - for the first year. After that - the renewal drops to $8/single and $10/couple.
I hope others can come on and help more - I'm just horrid at palpating.
BTW - when did you try to mate her? How long has it been - and how long have you had her?
