Sounds like what happened to my hamster, who I'm almost sure died from internal bleeding. :/ He got going in his wheel so fast he spun himself out of it, and as near as I can figure, hit the corner of his plastic sleep box, and I found him the next night laying in his nest, with a pool of dried blood, which, upon investigating, had come from his genital region, just like your hamster. So....there's probably nothing that you can do.. it sounds like she's getting close to that point, anyway :/ Animals who know they're gonna die don't typically eat. You could try syringe-feeding her apple sauce(I actually saved a hamster dying from malnutrition by doing that), just to get his body energized. Or if you have it or can find it, some pure berry jam, without added sugar or preservatives.
Is her cage set up in any way that she could have fallen, or accidentally thrown herself onto something that could've caused internal bleeding? Hamsters are generally pretty hardy - mine have taken countless falls that SHOULD have seriously injured them, but all they did was take a few minutes for a time-out, and were back to normal. But there are occasions, such as with my hamster Zodi that I mentioned, and possibly with your hamster, where they just can't shake it off.
Don't feel bad, hon, these things happen. And don't worry, at least as far as I'm concerned, not having that kind of money for a vet doesn't make you any less of a concerned, and well-meant pet owner. It's just rotten luck, is all. It's not your fault - like I said, it sounds suspiciously like what happened to my hamster, and I didn't see him running around his cage for 2 days, and when I decided to investigate, he had died. Just make her as comfortable as possible, make sure she's warm, and try to get some pure raspberry jam or apple mash into her(mash the apple yourself - applesauce bought in-store generally has added sugar and other things).
