6 months of trying is not unusual. When she starts getting into "years" then start feeling bad and she should probably be seen by her Dr. It took my hubby and I 6 1/2 years to conceive our first even with IVF help and then we still did it on our own. Coming off birth control can sometime hold you up,
If she wants someplace to hang out online to have "Cycle buddies" and other things, she can start at American Pregnancy Association's website/forums. Once she has been trying awhile if she runs into more snags I can recommend a great "infertility" site for support.
For now though, just be there for her and try to be understanding if she gets upset over other peoples children and her lack thereof.
