Eh, yeah I know. & you're right.
But, just throwing it out there, there are bc pills that cause ovulation to cease, or thicken the cervical mucus making it difficult for sperm to reach the egg. And the plan b pill prevents an egg from being released. [granted it also thins the endometrium, and there are bc pills to do the same, but they are not guaranteed abortifacients, unlike the chemical abortion pill.]
