Docs, wanted to know if i can get pregnant on ortho tri cyclen (ethinyl estradiol and norgestimate) if i took one pill one day layer than i usually do?

Should be fine: It probably won't make a difference, but you do want to try to take the pill every day. Take the missed pill as soon as you remember and take the next pill later in the day or evening. One pill shouldn't make a big difference. You may spot a bit and if you want to be certain to avoid pregnancy you could use a second means of BC, for instance a condom

Possible: but not likely. I would use condoms as a back up measure for the rest of the pack to be safe when you miss a pill
