I just started my first pack of Tri-cyclen Birth Control Pills. It says on the box that I should take it at approximately the same time each day, so I take it each day somewhere between 9-11pm. My friends have been telling me it should be at the EXACT same time each day. My bf and I have not engaged in sexual activity yet, and I know that it takes about a month before the pill becomes fully effective, but since I did not take it at the exact same time each day since I started taking the pill, how much longer must I wait before the pill is fully effective?
Thanks
