Sharp pain in lower back?

Ali • TTC #1!
Earlier I got a very sharp, very painful pain in my lower back, towards the side.  It felt more in my back than in my front/pelvic area, where I normally get cramps.  Basically, it felt like someone was stabbing me repeatedly.  It only listed for maybe 10 min, tops, then went away.  Those who have felt mittleschmerz, is it like that?
