Advice please

I have my 12 week appointment tomorrow and Im terrified of getting bad news that something has happened and I missed it..

I have no bleeding or heavy cramping(usually no cramps, if so light). Most days I have symptoms and some days nearly none. My belly is hardening and I have a little belly coming, almost no bloat.

I guess hearing about it happening terrifies me. I have had a previous miscarriage around 6 weeks and I have a history of Depression and anxiety.

Any advice on how to ease the anxiety? I dont want to be worrying anymore.:/
