I would imagine your mother knew before she married your dad that she would not be allowed to participate in the ceremonies and accepted it. Now, the ACLU and a host of other liberal activities would try to convince her the system was trampling on her rights.
Or that an abortion would be necessary.
Well, you're wrong about that. I can't even imagine what would motivate such a stance.
BTW, I was pregnant when I graduated -- from law school, and I got a lot of cheers, myself. It is something to be proud of, regardless of whether you're 18, as my mother was, or 34, as I was. Like my mother, I not only finished, I excelled.
And yes, if you try to keep a pregnant woman from participating in a graduation ceremony, I'd be tickled pink to sue you so fast your head will spin, and I'll kick your ass up one side of the courtroom and down the other. ;^)

Not that I support the ACLU necessarily, but why should someone have to choose between being married and pregnant and accepting recognition for academic achievement?
