Dr appointment 😢😢

So today went in for my weekly visit. I am 34 weeks and 2 days and am consider high risk due to baby trying to come early at 32 weeks. Was in the hospital for 3 days and they where able to stop contractions and keep her in. Today I’m dilated to a 2CM and 100% effaced and Dr said she’s as low as she can go! On a good note baby is measuring at 35 weeks exactly & already 5 pounds and is practicing breathing on her own! Everything was going great till we where hit with “your baby has extra fluid on her brain” she has about 13mm fluid on her Brain the normal is 11/12mm. There not really concerned at the moment they want to be able to monitor it and go from there, there hoping it will just go away in due time and if not possible some invasive surgery which the Dr said they do everyday. Other then that they told us baby was healthy and had a head full of hair! Prayers for our baby girl I hope she’s born healthy even if she does come early. Anyone’s babies came out with little extra fluid on the brain?
