My boyfriend and I do use protection. I had recently come off the pill in January because I was constantly bleeding towards December end last year and it was constantly messing with my emotional health. Saturday early morning (2am) my boyfriend and I had protected sex, but the condom slipped out inside me and he did not ejaculate (he told me firmly after I asked him). I was still paranoid about pre-ejaculate so I took Plan B around 5pm later that same Saturday.

Sunday at 9pm the exact same thing happened, the condom slipped out inside me again (and we both tried our best to keep it on but I guess we just didn't have the right sized condoms). He didn't ejaculate, however again there is pre-ejac. Is it necessary to take another does of Plan B?
