Hi.. Thank you for choosing Healthcaremagic.. Headache, nausea and vomiting are most common side effects of ipill which has to come down in few days..Ideally its taken with antiemetic(emeset tab) before taking tab.. Kindly visit a physician if nausea doesnot come down.. There is no relation for frequent stools..you might be having GI infection.. ipill may cause increased tenderness of breasts than usual and periods may be irregular.. Visit an OBGYN for breast discharge.. Its adviced not to take ipill frequently as its associated with many side effects with repeated use.. Hope its of help to you..Feel free to ask if you have doubts further Thank you
