Marsupials. Marsupials terminate their own pregnancy in a manner that is somewhat similar to humans.
Basically, all marsupials give birth to their offspring extremely prematurely by mammal standards. And the rice-grain-sized fetus crawls it's way up to the mother's pouch to finish development. If the mother doesn't want to be pregnant, she will often simply flick off or eat the poor little thing.
But, the suckling period in the pouch isn't pregnancy. Tho, the Joey creates a seal on the chosen nipple for 2 months thus the consensus that marsupials have two wombs.
Obviously it's not a perfect analogy. It's still the closest thing there is. Deciding you don't want to be pregnant halfway through early development.
