How To Avoid Unwanted Pregnancy After Having Sex?

On June 13 i had sex with my husband and unfortunately the condom broke. The same day three hours later i went to see a doctor and i told my doctor what happened and i told her that i don't want to get pregant. so she prescribed me to take yasmine contraceptive pills. she told me to take 3 doses 2 tablets each every 8 hours. so 6 all together. I had throw up after i took the second dose maybe be after half hour. Now i am still worried because my period date is around july 2. Can you tell me if i can take any other pills so i can get my period sooner and not be pregnant. thanks
