Does EC have any long-term or short-term side effects?
EC has no long-term or serious side effects and it is safe for almost every woman to use. Some women feel queasy or vomit after taking EC. Other side effects include headache, dizziness, tiredness, breast tenderness, or lower abdominal pain. Side effects should not last more than a day or two. Some women find that the extra hormones in EC cause unexpected bleeding. Don’t worry – it’s not dangerous or abnormal! EC may also cause your next period to come early or late.
