Is oral medicine safe for abortion?

Question
My wife is 33 years old and we have two children of 6 years and 2 years old. In between our two children my wife conceived 4 times. As we were not ready for the second child we aborted it by oral abortion medicine. Last year she had undergone a surgery for gallbladder stones. At the same time she was also operated for tubectomy. Now she is pregnant again since 2 months. Can she abort again by taking oral medicine for the 5th time? What precautions should we take while aborting?
Expert Answer
B
Your wife should be examined to rule out an ectopic pregnancy (pregnancy outside uterus). In such a case, medical abortion is contraindicated. If it is intrauterine pregnancy, then medical abortion is possible till 7 weeks of gestation.
