The My Wikitree menu is at top right of every page. Click that, and then scroll down to my profile which will take you to your profile
Once you are on your profile you click the black Ancestors button to see your family tree.
I see that you are not yet connected to the global family tree. You will need to continue to add more ancestors and relatives - especially siblings of your parents and grandparents (and their spouses and possibly children) - in order to make a connection.
Wikitree does NOT autopopulate the global family tree.
