Effects of Low Progesterone on Breastfeeding

Hello.  
I'm looking for someone that can help me find some answers.  I am 36 and about to have my first child.  My husband and I tried for a long time before we ended up finding out that I don't produce Progesterone and that's what was keeping us from getting pregnant.  I was in my breastfeeding class the other night and learned that it is very possible that my low progesterone levels may have a negative effect on breastfeeding and that I may not be able to.  Can anyone confirm this?  Can anyone please give me some information about what you may know about this subject?
Thank you!!!
