Lumpy Breasts

[TTC12]

I was wondering what peoples breasts feel like. It’s hard to know if what I feel is normal ( some fat, lumps and sometimes smooth pea like structures). Both breasts feel the same. I can’t find anywhere online which suggests what might be normal- other than everyone’s is different. Are you supposed to be able to feel milk ducts, or only if breastfeeding? Sorry for ramble. Thanks

Mine are very lumpy inside. Had to go to the doctor a few years ago for something and when he examined me he commented how lumpy they are 😣. He said it would be very difficult for me to be able to feel for worrying lumps (cancer etc) as they would be difficult to distinguish from the other lumps.
I couldn't breastfeed (didn't produce much milk) so not sure if that is related to the lumpiness or not.
