Hello dear Understand your concern. Ellaone is a emergency contraceptive pill Used in unprotected sexual intercourse. It is 95 % effective if taken with in 72 hour of unprotected intercourse.. Following are the side effects of morning after pill. It will remain for for 4-5 days Delayed or irrecgular menstruation 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 be side effect of pills. Drink more water Take rest Take healthy diet Eat fruits like papaya, orange, pomegranate Avoid stress, alcohol and excessive tea and coffee Start exercising like running, yoga and relaxation exercise. maintain hygiene after sex and urination If bleeding will not come go for pregnancy test to diagnose pregnacy as chance id only 5 % If it is positive and you do not waaant But you can use progout abortion kit up to 3 months of pregnancy Hope this may help you.
