please advice me on fraternity rushing

I seriously don't know when are the rush events. On the first week I visited pikes dx and delta upsilon and sig eps

Spoke to the guys dx. Pike just showed house and got name and number on computer but haven't heard of em

Dx got name and number and invited back but I wasn't interested

Other houses I just went and spoke to the guys and hung out

Problem is some houses I wanted to visit I didn't get too. Now it's the 2nd week and before I had a flyer that listed dates and time for rush but I don't know anymore

I am new so I don't know anyone ATM and I don't want to miss on stuff and rush then not getting a bid

Btw fraternities that store name n number on laptop but never contact u wats with that
