Greetings Veronica!
Are you using an app to access Gmail? I do, and sometimes I find that my program shows no spam, but if I go straight to Gmail via the web, that spam folder will have many emails in it, and every once in a while it’ll catch something I actually want. Usually some sort of login information or confirmation code.
So if I don’t get something I’m expecting, I’ll go straight to Gmail and check the spam folder, and if find what I’m looking for, I make sure to mark it as “Not Spam”. Sometimes this works for future emails, sometimes not, but at least I know where to go look when necessary.
I don’t know how long Gmail keeps what it thinks is spam, and it’s been long enough that Gmail may have deleted it by now, but maybe this can help you in the future.
Since Henry responded above, you’re probably in good hands and he’ll get you fixed up. Please keep us posted!
Cheers!
