Mom's of twins born between 32-34 weeks

Did your twins have to be in the nicu? If they were how long did they stay at the nicu and what issues if any did they have? I am 31w1 day and I had some Braxton hicks Contractions last night and some on and off today. I have this feeling I'm going to go into labor around that week. I know it sounds totally strange but it's just a feeling I can't shake so I want to be prepared for whatever comes.
