anyone else experience this?

I am currently pregnant with my 3rd and due In less than 2 weeks. Ever since my first pregnancy I have never experienced any sort of breast pain, soreness or leaking. My breast have never grown or anything. I struggled so much with my 1st because of course I wanted to breastfeed. I was not successful and I tried pumping and sat there for hours with not a single drop. My daughter was not gaining weight and my Dr said to go ahead and start formula. Best thing I did. So with my 2nd I didn't even try because like my first there was no changes with my breasts and now woth my 3rd is the same way. of course I'm going to try but I was wondering if anyone else has had this happen and were you successful with breastfeeding. I have flat nipples as it is and the shields didn't help.
