As pointed out, Project Rachel is a good starting points.
There are organizations that exist for the very purpose of helping women in your situation, and the Catholic pregnancy center you mention can probably put you in contact with some of these.
Also, if you make contact with just about anyone in the Knights of Columbus. Look online for the state officers, or someone at your parish or a nearby parish. Or google “Knights of Columbus General Agent” for your area–the insurance operation will keep a staffed office, and they will be eager to help. For that matter, if you call our headquarters in New Haven, CT, I am certain someone will get involved.
Another resource would be the Newman Center/Club at any of the local colleges.
