Freaking out hsg test

I have my HSG test tomorrow. So anxious to see if I have any blockages. Im not sure what my options are e aither way. What can I do if the find a blockage. What can I do if they don't find anything. Im just so ready to be a mom ok never thought I would have so much trouble. Feel like my life is missing this huge aspects of my life that I have always wanted what if it never happens and I can't have children.
