5 weeks no symptoms?

So I’m about 5 weeks pregnant and have absolutely no symptoms beside missed period and a bit of bloating (but I’m on holiday, so been eating a lot).

I remember that with my first I had sore boobs and nausea quite early (just can’t remember how early).

Of course I’m immediately freaking out, can’t do blood tests and will be back home only in two weeks.

Is anyone not having symptoms at all?
