Is that safe to used cytotic to abort for 3 weeks pregnant?

Depends. Abortion is only safe if you do it under a doctors supervision so you have someone to contact if you bleed too much or if something goes wrong. This is a medication that can make you bleed too much if you take the wrong dose. Women have died from it when they took too much because the abortion failed the first try. If it doesn't work you have to see a doctor right away and not try again. Cytotec have a higher failure rate then the combo of medication, FDA-approved, of Mifepristone and Misoprostol. Not all women can have a medical abortion, the doctor decides based on your health.
