Dry cracked nipples

So weird question

My nipples have been super dry and cracked for like my whole pregnancy - ive tried everything

Nipple balm, lanolin cream, vitamin e lotion, Coconut oil - NOTHING HELPS

I’m having my c section on Wednesday and I’m worried that my baby won’t be able to breastfeed because my nipples are so dry and cracked

My doctor doesn’t do anything at my appointments except measure my belly

Suggestions ????
