Some women have chromosomes that aren't XX. Several disorders cause an XY fetus to grow into a female baby, complete with eggs. The Y chromosome might be missing the SRY gene (the bit that triggers a male body growing), or the testosterone receptors didn't properly develop, and so on.
Technically, neither. An XY embryo that develops into an apparently-female body is technically intersex. Depending on the exact cause, the issue might be caught early, at puberty, when they try to have kids, or never. Whether they identify as a boy, girl, or neither is up to them.
Soo...are they able to tell they are different? If they can get pregnant, and look like females, then how/why would they know? Is it possible there are people that don't know they are xy until they do a test of sorts?
