Can't stop eating 39w

So I am due in 4 days and I've been constantly hungry for the past 2 days.

I've drunk 2 litres of water and 2lr berry juice to try to feel full as well as snacking inbetween regular meals each day.

Nothing is filling me.

I've eaten healthy and normally throughout the whole pregnancy but gained 17kg (I've been unable to workout) but haven't felt so hungry before.

Anyone else have moments of just total hunger?

Is this a sign?

Anyone have solutions for such hunger?
