HELP!!

So I know this is for April Babies but I have a question.....

Has anyone every recieved certified mail before? If so what were they for?

I got a a notice saying I had certified mail, but since I was not at home to receive it I have to pick it up tomorrow.

I have no idea what it could be and I'm not sure if its because I'm pregnant, but I'm extra stressed out about it.

Please help lol

My mind is racing about what it could possibly be and since I'm 30+2 I'm praying it's nothing that could be saying I owe money. I'm stressing out about this.

Sorry I'm being dramatic...
