Hello and welcome to HCM,     
I am Dr Nilajkumar a consultant gynecologist and I will be helping you in your queries.

The pill containd 20 mcg of ethinyl estradiol in each pill. Emergency contraception using oral contraceptive pill must contain at least 100 mcg of this drug in one dose. So you must take 5 pills at once and 5 after 12 hours for it to be effective.
It is effective in more than 95% cases if used within 72 hours of unprotected sex and the earlier it is used the better is its efficacy.
However it may cause nausea and vomiting leading to failure if the pills are vomited out. So you may try using an antiemetic drug like doxinate with the pills.

Hope this was helpful.
Feel free to ask any further queries and I will be happy to help.
Thanks for using HCM.
Have a good day.
