Hello! I am 26, taking Qlaira (4th pack). The 1st pack went well. During the second pack I had a bleeding after 14 th pill. During the 3rd pack I had a bleeding after 21st pill. During the last 4th pack I am now having a bleeding after 11th pill. i have no other side effects. Should I quit Qlaira or try taking it for another couple of months? i am worried about this irregular bleedings.
