Change in discharge

Anyone else have this? 22+1 I woke up with a little puddle in my panties like water, no smell, and throughout the day my discharge was watery instead of the usual milky white. And always feel damp. So I was worried i was leaking amniotic fluid went to my doctor and she checked me out and said it was just normal discharge increasing but getting an ultrasound next week just to make sure no leaks. But still worried! Trying to convince myself it’s pee but does not smell and no colour, and it most when I wake up in morning.
