Slightly OT. Pregnancy, estrogen, progesterone, DIY

OK I need your help guys. I know its very OT but I know some of you fellows have PHDs in this subject. My condom broke last night and I live in a country where birth control is available but morning after pills, and ru486 are not. I know this pills are just a higher dose of birth control pills, so my question is can I make a dose of morning after pill with birth control pills. I dont know much about cycles of girls either but I know its been 8 days since her period. Sorry for the off the topic subject matter but I do know it is some linked to what we generally talk about.
Cheers and many thanks for those who help me out.
