Might have baby early at 33 weeks ..

I went to the doctor today and she said that my amniotic fluids had decreased since my last visit which was a month ago. My midwife told me that when I go back for my next ultrasound next Monday May 4th they will let me know if I need to be induced or not. She said my baby is just fine tho and her well being is fine , her head circumference seems to be  a little behind but she doesn't have any disorders or anything. Anyways she told me to cut my hours from work and rest more and try increasing my fluids and drinking grapefruit juice.  I am just so nervous because I want my baby to be okay. And I don't even have her room finished yet. She's not due till June 20th. Any other moms that were in this situation ?
