Can anyone else relate? Worried mama here!!

This week when I had my 32 week ultrasound I found out my lil girl is 4lbs 4oz with a full head of hair! ..However I also found out I have what they call Polyhydramnios, (too much amniotic fluid), which in most women is caused by gestational diabetes, although I do not have that so we do not know what the cause of it is!! Now from here on out I have weekly visits with ultrasounds to check levels & to make sure my baby is ok. -- Can anyone else relate?! I am stressing & worried something might be wrong or go wrong. Please tell me your stories if you've been through this!!
