2littlegirlz, no you didn't peeve me off lol.
I too had to try several different brands before I got the right one, and in the end the normal pill wasn't for me - migraines.
I had the mini pill, which only contains one hormone not 2.
I totally agree it is her body and for her to decide what she wants to do, but it is also nice to see a guy with concern that just a condom may not be enough, which was why I suggested spermicides as another precaution.
While 2 condoms is bad news because the friction between them is more likely to lead to tears/splits, a condom and a cap/diaphragm with spermicide will add to the protection, if the condom was to break/fall off.
I would never recommend stopping using condoms because she is on b/c. However, I did have to find hypo-allergenic condoms, because I was allergic to the rubber/latex in standard one's

so sore afterwards (tmi).
But yes, although unlikely for most people, if you aren't prepared to accept a pregnancy then abstinence from sex is the only sure fire answer.
Even sterilisation isn't 100% - my mom concieved my youngest brother (16 now) after she had her tubes tied
