What could the side effect be you used cytotec pills to clean your self not knowing you were pregnant?

There is no need to "clean yourself". The body takes care of that itself. So don´t try to excuse using Cytotec for anything but abortion if you are a woman. Only men uses it for ulcers and women only uses it for abortion. 2 weeks after sex you can take a pregnancy test, not before. If it is positive you can then use Cytotec in the right dose for abortion if you wish. If you do not have a abortion provider where you are you can always go online to womenonweb. If you do use it without being pregnant it will cause severe cramps and pretty much make your period start all over again but it will be longer and you will bleed mre. If you have no period but is not pregnant there is other medication for you.
