It might have been protected at first, but as soon as that condom broke it became unprotected, and that leaves you at risk of pregnancy. Whether there was pre-ejaculation or proper ejaculation. You've missed a pill or two, and so you're not fully protected on that note, which leaves you open to becoming pregnant. The urethra thing doesn't matter - there was still pre ejaculation so that can still cause pregnancy.
but we did have protected sex, it just broke and we pulled out as soon as it broke. so yes, precut probably was inside me, but he said the last time he ejaculated was about a week before, so the urethra must have been rinsed out by urine plently of times before we had sex. so my odds are really small right?
Even by pulling out, you can still become pregnant so you'd be better off not pulling out. Chances are pretty much the same to become pregnant.
Not taking your pill as directed means that you're not fully protected, and so yes, pregnancy is possible - especially having unprotected sex.
All you can do is wait, and if your period shows on time then you're probably okay. If not - take a pregnancy test.
