Hi, I understand your concern and wish to clear your doubts. Unwanted kit is one of the emergency contraceptive pills intended to be used to prevent an unplanned pregnancy in the event of unprotected sex, forced intercourse, rape or failure of contraceptive measures being used. It is an oral pill and contains 1.5 mg of Levonorgestrel that helps in preventing an unwanted pregnancy if taken within 72 hours after the act of penetration, though it will not prevent a pregnancy if implantation has already taken place. In your case your wife is in 5 weeks of pregnancy and i doubt if this pill works for her. The common side effects of Unwanted kit are fatigue, abdominal pain, breast tenderness, nausea and vomiting . Some women also get headaches – though all these discomforts should go away in a day or two. Gastrointestinal issues may also be observed Because Unwanted kit works by restricting the natural course of hormones, her periods can either be early or get late. Taking Unwanted kit repeatedly can harm the course of her menstrual cycle Vaginal discharge is also observed by some women who take emergency contraceptive pills. Regular use may make spotting a constant issue Emergency contraceptive pills that are hormonal can lead to hormonal imbalance in the body. This can further lead to a series of headaches, mood swings, hair loss, unexplained weight gain, skin allergies and acne. I suggest you people to take a gynecologist opinion, who can help in safe termination of pregnancy. Regards Dr Santosh kumar A
