Cytotec (Misoprostol) alone WILL NOT work for a medical abortion. Cytotec causes softening of the cervix and helps "prepare" the uterus for delivery. Cytotec alone CAN cause an abortion, but not properly using both drugs for a medical abortion can result in a failed medical abortion or parts of the pregnancy retained.
Two pills are given for a medical abortion. One is Cytotec (also known as Misoprostol), the other is Mifepristone. Mifepristone is the actual abortifacient, or drug that causes the actual abortion. Mifepristone causes the death of the embryo, causes the uterine lining, placenta, and any other tissues to separate from the uterine lining, and causes the bulk of the uterine contractions. Cytotec, as stated earlier, causes softening of the cervix and helps stimulate the uterus to contract (it can cause mild uterine contractions).
You should never attempt an at-home (medical) abortion without supervision from a doctor. You should not buy abortion pills from online pharmacies UNLESS you have a prescription for them and they are REPUTABLE. Taking the wrong amount of either drug can cause you bodily injury. Not taking both drugs can cause complications. In places where abortion is prohibited, I understand your need for finding information upon how to obtain a medical abortion or the pills for a medical abortion. I cannot stop you from buying at online pharmacies, I can only urge you to do research on any pharmacy that you might wish to buy from, and make SURE you read up on how to take abortion drugs properly before buying them. There are resources via the internet, you need only look. I suggest you do research first via medical hubs as they are more accurate. Remember, the internet cannot replace a doctor. And I suggest that if you have already taken the pills, be seen by a doctor ASAP. They cannot "tell" if you have had an abortion. If abortion is illegal, all you need to do is say you think you have had or are having a miscarriage.
