Plan B After 22 Hours

my partner and me had sex and the condom broke on us to our shock. it was my 2nd round so when i came it wasn't as hard/strong as the 1st (i used a diff. condom yes before anyone asks). she wasnt on birth control as she is slated to have a doctor's appt. Friday to get some. after the "incident" she took stuff out and kept getting this white stuff but it could have been her c*m, and when we compared each other's it didn't feel like mine. in fact there's a chance i didn't *** in her. however there is pre-ejaculation of course.

long story short, we took action. 22 hours later (she had to go to school and work bac-to-back bf we could do anything). we bought new condoms, she got VCFs, and she took a plan b pill 22 hours after and just took the 2nd one 12 hours later. i know the quicker you take it the higher the chance, but i also heard w/in 24 hours is a really good thing. how worried should i be?

btw her 1st day of her last period was 09/28/2009, and she claims her cycles the last 6 months have range from 30-35 days. so she's prolly in her fertile period.

helkp? suggestions? comments? i'll update
