Old underage Account without a ea account connected

I recently came back to swgoh after a long break. I wanted to log in the webstore but discovered that I don’t have the ea Connect Option in the settings.

After some research I discovered that the problem was that I had an underage account. The problem is that I don’t know my email adress that I used to create the account because It’s not connected to an ea account. 
Is there any way to fix this ?
