I have been on the Oren tri cyclen lo pill since November. I was on my third pack , week 2 pills . I recently just had unprotected sex with my boyfriend for the first time on January 24 which also is my ovulation week . I missed taking a pill regular time Tuesday January 22 but I took it around 1 am January 23 and took my Wednesday pill on time but had unprotected sex the next morning .
