What does implantation feel like?

I know it's early... like crazy early.. I felt this kinda like a pin got stuck into my abdomen today and feel this pulling, and tingles.. Would it be implantation? It's been 7 days today, nd it will be 3 weeks before I can take a test.. just asking cause if it could be I want to be able to let my fiance know so he isn't blind sided if it is... that and I talked to my mom about it a little and she was the one that asked if I was.. and when I looked back it is possible that I could be..
