How many days does a three week pregnancy take to abort with cytotec?

If you take the pills as you are supposed to it will be done in one day. I do hope you have researched this and got information by your doctor including risks etc. More info in the link below from womenonwaves.

If you don't use enough it is possible that you can still be pregnant but unfortunately you may have complications to deal with. In rare cases a smaller dose can still cause an abortion but it may take as much as a week, and can even be pain free although the bleeding is plentiful and you pass huge clots and clumps of cells.
