If there was only one sorority doing informal recruitment, I wouldn't worry too much about that not working out. Usually, the allowed number of bids during informal recruitment is pretty low and women who already have strong chapter friendships tend to be the ones who get the bids (for example, the chapter I advise was only allowed to take 2 new members this winter, and it's been about 3 years since we were under total after December graduation and even allowed to participate). Because the number of allowed bids was so low, the chapter really promoted "going Greek" at their open house, being friendly, and encouraging participation in the upcoming formal fall recruitment.

I would say being released by all chapters after the first round of fall recruitment is more concerning, but that's where getting recs would help. Also, while you definitely want to get involved in other campus activities, you'll also want to join organizations where you will meet sorority members, if your goal is to join a sorority. If there are sorority women in the feminist and LGBT groups, great; if there aren't, then that may not be helping you make connections/friendships with the sorority groups you're looking to join. Of course, you should join organizations that promote your own interests and passions. Be true to yourself, but keep in mind that participating in a "neutral" academic honor society for a club for a major, a hobby/special interest group, or a volunteering group generally exposes PNMs to a more diverse group of women than they would typically meet by limiting their participation to campus organizations with religious, political, or activist affiliations.
