Is it natural to have a desire for a baby and then completely lose that desire after 28.they're cute an I love em but it feels cruel having a baby in

No woman should feel guilty for not wanting a child. We’re not all born to be baby factories.

Looking at the school fees these days, wailing babies, eternally harried parents and strained marriages is enough for me

You're like 70. Will your eggs be fine?

Maternal instincts is common in both gender while paternal instincts are quite different with ambitions. Yes babies are cute and lovely , but we can see many playing with em like dolls and lose intetest later. We get the instinct as psychologically we feel like reincarnating and transferring life to future. So depends on your will power. But if you don't feel you can take responsibility for that long, adopt a single mother, so you get both and the child has mother anyway and that you didn't beget to give up half way.
