If you figure, on average, the baby will gain half a pound a week and you have 7 more weeks to go, that will put her at 7.5 pounds- a very average size baby. I wouldn't get any more preemie stuff. My 7 lb. 5 oz baby never needed preemie, just newborn. My 6 lb. 8 oz baby (who lost a lot of weight and gained VERY slowly) did use preemie clothes for about 5-6 weeks. I think you're fine with what you have, just be sure to have newborn (as opposed to 0-3 month) sizes :)
