Hi Thank you for asking HCM I have gone through your query.The side effects of I pill will be for short time.They dont have long term effects. You might get nausea or vomiting after taking that.You might also get a headache, feel tired or dizzy, have some lower abdominal pain, or find your breasts are more tender than usual. If you do feel this way, it should stop within a day or two. Some women also find that the pills cause unexpected bleeding; this is not dangerous and should clear up by the time you have your next period. The pills might also cause your next period to come early or late. Hope this may help you. Let me know if you have any further query.
