Inverted/flat nipples?

I’ve had inverted nipples my whole life and am now due with my first in March 2019. I’ve heard many times that women with nipples like mine can’t breastfeed, however I would really like to! I realize it may be a bit harder for me than others but I’m just wondering if there are any women here that have either inverted or flat nipples that could give me some advice or even just some positive stories.

My sister has flat nipples and she was unable to breastfeed my nephew 6 years ago and I’m worried that I’m doomed.
