Low amniotic fluid around twins early pregnancy

sammie

So to day I had another scan to check for heart beats... Both babys have them

They are now conserved that there is not enough fluid around them

Is there anyway I can increase this I no i was told to drink lots ov water

Baby 1 is measured at 6wk1d

Baby 2 is measured at 6wk2d

But i should be 7 weeks

Is this a bad sign
