Unusual back pain and vagina pains

I posted this to general health and life style as well but thought i might get more responses here. Serious back pains and vagina pain

So late last night i got woke up but a sharp pain in the middle right of my back. I thought maybe i had to go to the bathroom (normally I just get some cramps if i am holding it) however that didnt happen. I finally decide to go lay back down on my left side and see if it goes away. I noticed when i stood up my vagina was hurting kinda like i had just had crazy sex with a dig junk (i hadnt at all). It went away after about 20 minutes. As far as i know im not pregnant, periods suppose to have my period in the next couple days, been cramping since yesterday. Opinions? Should I be concerned?
