I don't know if i got my girlfriend off......?

We have been going out for a while now, we have had many times and she has really enjoyed it, but she has never had an , or that is until now (we think). last time we had she said it was different. This time i ended up with scratch marks all over my back from her grabbing on so hard, a giant hickey and she said her hands went all numb and she couldn't remember doing any of it. She said it was different and that it was really awesome. Do you think she hit a climax?
