Of course being born 12 wks early was tough but I had an incompetent cervix thus the early delivery and 7 weeks of hospital bedrest were critical. Most triplets are born on average at 33 weeks but doctors will schedule c-section for 36 weeks. I have friend who made it to 36 wks but this is very unusual. Most women go into labor at about 34 weeks and then the babies will spend between 1-2 mos in the NICU.
The only time you might want to be concerned if it is more than a month either way. Full term pregnancy is bettween 37-40 weeks not exactly 40 weeks. If you have a baby at 37 weeks they still consider it full term. You're due date is at 40 weeks and 37 is considered full term. But there is only one month with exactly 4 weeks(most years) so it still is about 9 months.
