there is a very good chance the baby will be alright, a lot of babies pull through it will just require a stay in the nicu typically
possible problems to expect would be breathing problems, temperature controle problems, feeding problems, possible heart problems, etc (none of these are for sure and theres other things too, im just trying to let you know so your not taken by suprise, i dont know how much you know and dont know about preemies)
and expect the baby to be small and like i said to go to the nicu, and the nicu usualy has some serious rules regualrding who can visit when and what has to be done
premature birth also puts the baby at higher risk for sicknesses later on (like rsv)
all that being said i hope the baby comes out perfectly fine!
