Pregnancy--we were taught, if we were privileged--was something awful that went with sex, just as AIDS and genital warts went with sex, unless you used condoms (and even then, be really careful). It was made clear that sexually transmitted diseases and teen pregnancy were simply not for us: We were to use birth control and go to college and if we somehow got pregnant too soon or with the wrong guy, we were to abort. There was no mention of the possibility that we might want to get pregnant too late. From the minute the dragon of our fertility came on the scene, we learned to chain it up and forget about it. Fertility meant nothing to us in our twenties; it was something to be secured in the dungeon and left there to molder. In our early thirties, we remembered it existed and wondered if we should check on it, and then--abruptly, horrifyingly--it became urgent: Somebody find that dragon! It was time to rouse it, get it ready for action. But the beast had not grown stronger during the decades of hibernation. By the time we tried to wake it, the dragon was weakened, wizened. Old.
