Hi, i'm 18 yrs old and i've been on Ortho tri cyclen for about four months now and i was wondering if it has started working yet i started on a random day and start a new pack every Sunday. However sometimes i forget to take my pills and have to make up with two am i fully protected if i have sex with my boyfriend without a condom on my safe days when i'm not ovulating? (i don't want to get pregnant) and also are you at risk of being pregnant only when you miss a pill in that particular cycle?
