Worried about MC still at 13w

I've been worried about MC on and off since ttc and getting pregnant. But now it's all I can think about, even though I know our risk now is really low. We're 13w5d.
​I went to a BBQ yesterday and there were 4 women there talking about babies, ttc and pregnancy. 3 of those had been through MC with their first. Now I'm super paranoid that it's going to happen to us. In my head I know it's unlikely but I can't shake this fear.
