Inverted nipples and breastfeeding baby number 4!

hello everyone, I will be 10 weeks pregnant on Friday. This is baby number 4 for us, but it's been 5 year's since my last pregnancy so for me, this is like starting all over again.... With my other 3 I tried really hard to breast feed, but I have inverted nipples. With my last one, I tried using the Medela soft shell's for inverted nipples, and it didn't work. Not to mention I don't exactly have small breasts either. They are fairly huge and awkward to work with, but I really want to make an honest effort this time... Is there anything that I can do right now while I'm pregnant to help draw them out ? Or should I just wait until the baby comes ??? I was told today at WIC by the nutritionist that specializes in breast feeding that I just need to wait until the baby comes and wear them or at least the last trimester and I need to try pumping to draw them out... I am just wondering if anyone else has had these issues..... And if so were you able to breast feed successfully, and how "??? I just need a lot of help....
