I took 3tablets of cytotec swallowed 1 and inserted 2 on a 2weeks pregnancy but it didn't work and?

Yes it can abort but it sometimes fails one can try a second dose and if it doesn't work she should do ultrasound to confirm whether she has ectopic pregnancy

Cytotec doesnt always work and when it doesnt, a woman generally has to have a surgical abortion because cytotec does affect the unborn child. There is a "black box warning" about this in the drugs insert. Cytotec is not a good drug for abortions because it can cause birth defects ifthe child is not aborted or it can cause only a partial abortion which can lead to hemorrhage. It can also lead to uterine rupture which can be fatal. It is supposed to be used in conjunction with mifepristone AND it should be done under a Drs supervision. For one thing, you dont mention using mifepristone and the doses you took probably were not high enough. If you take more now, you risk not only losing the baby, you risk killing yourself or damaging your reproductive system so badly you'll never have children.
Here is what the literature states:

Do not take misoprostol for the prevention of stomach ulcers if you are pregnant or if you might become pregnant during treatment. If you do become pregnant during treatment with misoprostol, stop taking the medication and contact your doctor immediately. Misoprostol is in the FDA pregnancy category X. This means that misoprostol is known to be harmful to an unborn baby. Misoprostol can cause miscarriage or spontaneous abortion (sometimes incomplete which could lead to dangerous bleeding and require hospitalization and surgery), premature birth, or birth defects. Misoprostol has also been reported to cause uterine rupture (tearing) when given after the eighth week of pregnancy, which can result in severe bleeding, hysterectomy, and/or maternal or fetal death. A pregnancy test with negative results will be required within 2 weeks of starting treatment with misoprostol, and treatment will begin only on the second or third day of a regular menstrual cycle. Also, appropriate contraception will be needed to prevent pregnancy during treatment and for one menstrual cycle following treatment. In some cases, misoprostol may be used under the supervision of a doctor for the induction of labor and delivery or abortion.

It is not known whether misoprostol passes into breast milk. Do not take misoprostol without first talking to your doctor if you are breast-feeding a baby.

You could not only lose this baby but you could also lose your uterus and never have another child again. Who ever told you to use this drug to abort did you a disservice. You need to consult with a obstetric surgeon and let them know that you took this drug. It is likely that you will need surgical abortion. It is extremely dangerous to use this medication and you should be worried!
