I didn't think the drug was developed until the late 80's. Are you saying you took it in 1953?
Sockmonkey:
Have not done research to verify, but believe like Hy Pylori was discovered in Australia was cause for 90%of ulcers was available for many years (Drug companies didn't want to lose profits or costs of developing other meds and OTC remedies for stomach problems.) So this is my belief with abortion pill. It was available in Europe for many years before it was used here legally. It was the RU 486. The year maybe off, it may have been 1958. It was just prior to the birth control devices that came out in 1960. Before that had to take temperature a lot for birth control. (failed a lot). I remember it being discussed at the time. Will do more research just to satisfy your question and my curiosity to find what is documented. US has many secrets mostly to make money for the "chosen few".
