Hello!I am 26, taking Qlaira (4th pack). The 1st pack went well. During the second pack, after 14-th pill I had a bleeding. During the 3rd pack I had a bleeding after 21st pill. And now during the 4th pack I am having a bleeding since 11th pill (4th day of bleeding now). The bleeding is not heavy accompanied by not heavy abdominal pain. Besides this I have no other side effects like headache, or anything. I dont know whether to quit Qlaira or not. Could you help?
