Birth control and baby crazy???

I've just finished my first month on birth control in a year and a half. I am suddenly baby crazy af. Like, I'm not in a place to want kids, and I'm certainly not trying to get pregnant, but holy shit I want to be so pregnant it hurts. My dumb animal brain wants a baby, but my smart human brain is like NO!!!! Is it hormonal? Is it being almost 25 and a nut job? Is it that I'm pretty sure I've started dating the man I'm going to marry? What's good, uterus? What's good?
