TMI WARNING - DO NOT READ AND COMPLAIN LATER:
Cycotec is not an abortion pill. It is used to induce labor (cervix opens up and contractions in the uterus starts). In the US it is only used mith RU-486 (mifepristone) which is a abortion pill. RU-486 will make the uterus lining break down and starve the fetus to death, Cycotec will help your body to expell the dead fetus.
The use of Cycotec is prevalent in Latin America, Southern Africa and the Fillipines, and are normally bought on the black market. It is a very crude abortion pill and will try to induce labor and expell a live fetus. It is however only successful in about 40% of its users but it is much safer for the mothers than back alley abortions.
In studies of birth defects in these countries, it was found that up to a third of babies with some birth defect was exposed to Cycotec. This is no indication of how dangerous it is for the fetus as no statistics are available of how many healthy children got born after a failed Cycotec 'abortion'. Because of the morals and ethics of Cycotec, there are no research done on it.
Your best bet is to tell your doctor about you taking Cycotec so that he/she is aware of it and can look for signs of problems. I am not sure what the laws in your country are on doctors reporting such things to authoroties and doctor/patient confidentiality so this is not legal advice.
