Getting ready for fertility consultation

I just got off the phone with the fertility office. They ordered me labs and a sperm sample for my husband. I have to call to schedule my hsg when I start my period. Then we will have our consultation. I'm so overwhelmed with emotions. A little nervous, a little excited. I'm hopeful and want to be optimistic but something inside me keeps saying this won't work. It will end in heartbreak. I'd love to get some advice and support. I don't know anyone else going thru this so I'd love to hear success stories, struggles. Also where do u go for free education, support and guidance. Thanks ladies!
