Hello dear understand your concern. First you can confirm pregnancy by Urinre HCG kit again after 5 days Or you can do blood HCG or USG to confirm pregnancy, because unwanted 72 is failed in around 5 % But It may be side effects of unwanted 72, note its side effects: Delyed period or irregular period due to hormonal imbalance. Nausea or vomiting Dizziness Fatigue Headache Breast tenderness Bleeding between periods or heavier menstrual bleeding Lower abdominal pain or cramps So I think It is side effects of pill. But If bleeding not come, Consult the gynecologist and go for USG. Avoid stress. Regular exercise like walking and relaxation exercise Avoid smoking and alcohol Drink plenty of water Eat fruits like papaya, pomegranate and orange. If pregnancy test is positive, You can still use pregout abortion kit till 3 months of pregnancy if you do not want pregnancy. Hope this may help you. Best regards Dr, sagar
