This is interesting. The abortion section doesn't seem to mention ye olde menstrual extraction. Some decades ago, I believe the early seventies, some feminists figured out how to basically get the whole "eject the sloughed menstrual tissues" part of the cycle over with in a simple procedure, rather than enduring the days of cramps, which I know make some women quite miserable, even debilitated. This can also serve as a first trimester abortion.
