I would like to know the medicine to avoid 2 weeks pregnancy?

Unsure : I'm unclear as to what your question is. If you want to avoid pregnancy, then birth-control is best option. If you had unprotected intercourse and want to avoid pregnancy then ideally as soon as possible taking a plan B is excellent. If you're two weeks pregnant and don't want to be pregnant, then medical abortion at this point is possible. This medication is called Mifepristone. See doctor
