implantation cramps??? please help!!

Am
Hey ladies so today I am 6 dpo, I've been having some mild twinges here and there the past 2 days but this evening I stood up out of bed and got a sharp crampy pain on my left side that lasted probably 20 seconds. It was sharp at first and then felt like period cramps. I also had that feeling(I don't know if some of you will know what I'm talking about) I think it's called lightning? It feels like sharp pains in my vagina. Kinda weird but that went along with the cramping and then it stopped. Any thoughts?? I appreciate it❤ also if this is implantation when could I test?
