rush again

I'm currently a sophomore who rushed several fraternities for the first time but never heard back after Zone Days from most of the ones I was actually interested in joining. I'm left with a few lower fraternities that I really don't fit in well with. I should've went to more Zone Days but I didn't. Would it be a good idea to just not join this semester and try some other fraternities in the Spring? Is it too weird and near-impossible for a sophomore to rush in the spring? Please help me out, I would appreciate it greatly.
