32 weeks and 4 days

Nyree • Got our BFP December 2014 and its twins!!
I just found out that Twin A is in the 3rd percentile and is considered very small. They are both head down but I was told that I most likely will need c-section because Twin A is too small to deal with the stress of vaginal birth and I may also need steroids to help develop its lungs. 
Just feeling a little devastated as I had my heart set on vaginal birth and I'm scared of a c-section. 
Anyone else in the same boat?
