Here is a list of DIY abortion methods I found:

Lifting of heavy weights;

Consumption of mutton marrow;

Consumption of dried henna powder;

Consumption of carrot seed soup;


physical exertion designed to bring about a miscarriage
abdominal massage

receiving punches, kicks, or other blows to the abdominal area

bellyflopping onto a hard surface, or throwing herself down a flight of stairs

attempted removal of the fetus with a coat-hanger or similar device inserted into the uterus through the cervix (the historical use of this method has led to instances of its use as a symbol against the pro-life movement, illustrating dangers of barring state-condoned abortion)

attempted piercing of the fetus with a knitting needle, crochet hook, hat pin, bobby pin or similar device inserted into the uterus through the cervix

insertion of a rubber tube or catheter into the uterus and attempting to suck the fetus out, or, alternatively, blowing air into the uterus to cause a miscarriage (if the tube or catheter pierced a blood vessel, this would sometimes lead to air embolism, which could be fatal)

ingesting abortifacients, Vitamin C megadosage, Pennyroyal or other substances believed to induce miscarriage

douching with substances believed to induce miscarriage, such as turpentine, clorox bleach, or lye, all of which could cause intense 

chemical burns (beginning in the 1960s, many women used Coca Cola for this purpose, although its utility is at best dubious)

vaginal pessaries

yoga

acupuncture at points linked to miscarriage

hypothermia (many women would lie for peroids of time in snowbanks, which could be fatal to them) or hyperthermia (women would lie in tubs filled with hot or even scalding water for periods of time, often while simultaneously drinking gin)
