gpa requirements

I'm planning to rush as a sophomore because I made a really bad GPA first semester of freshman year. My parents were going through a divorce and my grandma passed away so it was a very stressful semester for me having to help out with the family. I'm bringing up my GPA now but it looks like it'll be just at/above the requirement by the end of this fall, but only by a tiny bit.
Any advice from anyone? Are there any sororities that are less strict about grades than others? I'm a legacy for Theta and Pi Phi so I'm pretty upset about my GPA. Thanks in advance to anyone who has some advice.
