Did I orgasm?

Okay so i have never gotten to the point of orgasming because my clitoris is super sensitive. But last night i was playing around and something strange happened. I found my sweet spot and i kept things going in that one spot and then all of the sudden my heart started beating out of my chest and my breath got ragged and my legs started spasming? it was like a weird tingly tickly sensation and then afterwards i couldnt walk because my legs were all wobbly. and immediately after i fell asleep. Now im not sure if this was an orgasm- because it wasnt like anything i had felt before but it also wasnt like most women who explain orgasms. So uh- any feedback?
