I've been on ortho tri cyclen lo for about three years now. I'm pretty good about taking my pills at the same time everyday around 8:15pm but about 6 days ago I was late and took it at 11pm. Then 4 days ago I missed a pill, the dark blue one, ended up taking it at 11am the next morning and proceeded to take my next pill of that day at the set time I had. I know this particular pill says that if you miss one pill you take it ASAP and no back up method is needed, but I was late a few days before that. 2 days ago I had unprotected sex with my boyfriend, he did not ejaculate. As of yesterday I started the placebo pills, should I be worried about the possibility of pregnancy? Or am I just being paranoid?
