Holy cow, I can't believe you're 35 weeks already! Wonderful. Anyway, you're in really good shape. Plus, by Friday, you'll be closer to 36 weeks. Even if your little one has a brief NICU stay, and there's a big chance he/she won't, it will be an entirely different deal than with a 30 weeker. There's much more maturity on their systems.
I had a friend deliver at 35 weeks (early labor) and her son had no NICU stay. Also, my sister-in-law just had a baby in November at 34 weeks and 0 days (placental abruption), and his NICU stay was only 12 days. I couldn't believe that his monitor rarely ever dinged. I know my son had a lot of desats and bradys at 34 weeks gestation, but he was a 27 weeker. It's amazing how different it is. Anyway, my new nephew had a couple days with a cpap, a couple days with a nasal canula, both on very low O2 settings, and then he was breathing on his own and just learning how to eat.
If I were you, if my doctors so recommended, I'd rather have a healthy 36 weeker out and be a healthy mom, rather than chance getting sick, which only puts the baby in destress and is a harder recovery for you. In the meantime until Friday, I'd take it easy and drink all the water I could! At least 2 liters a day. Check this out: http://www.ncbi.nlm.nih.gov/pubmed/12698777
Wishing you the best!
