I agree with Gail 100%. You say you didn't see any blood and blood, being red and all, is pretty hard to miss. Moreover, you never actually came into any intimate contact with her or her fluids, so it's quite impossible to get HIV in this way. Finally, of course, you do not know if she had HIV in the first place, and if she didn't have HIV then she couldn't very well have given it to you.
Please try to stop obsessing over this. You were not at risk and no testing is necessary.
