I've not tried to conceive yet, but I fear my breasts are hypoplastic.

They seem like they started to develop normally, but began to change around age 18. I seem to have somewhat "normal" breasts close to my body, then they become tubular about halfway out from their full development. I really pray that the small amount that did develop will be sufficient, but I've worried for years now that I won't be able to breastfeed, like I really would love to do.
However, if I can carry children to term, I'll be incredibly thankful!
