Hi I have been using Tri Lo Sprintec for about 2 months now and it is my first birth control. I understood that it was the generic form of ortho tri cyclen lo the first month I experienced breast tenderness and spotting. I feel fine using the bc but when I wanted to refill my prescription for my 3rd month I just found out they discontinued it. now my question is I did get the brand ortho tri cyclen lo which is more expensive can the birth control still be affective if i change my time taking the birth control? i usually take it at 9p but I want to adjust it to 4p when i start the new ortho tri cyclen lo. can someone please help me solve my dilemma? I'm taking birth control to regulate my periods and make it lighter.
