I was pregnant during my entire last year of university studies. It was great, because I memorised and understood the information better. So the pregnancy helped my intelligence

.
But regarding the kid, I think he now knows more about logistics, distribution, marketing, management etc.
Really, my mom was pregnant while teaching Physics and Chemistry in a highschool. I must say her passion for physics really marked me as a fetus, cause all my life I loved studying it and I'm really attracted to it, even though I'm innerly inclined more to foreign languages, computing and others.
I don't know, amath, maybe the real question is "Do your studies fit the role of mother that you choose to be? Can you manage both after the kid's birth?". Cause surely the child will benefit, somehow, but you shouldn't worry about that, just do what you feel like doing if it suits you.
