Hi,I Had Sex With My Wife Using Condom And It

hi,I had sex with my wife using condom and it was 7 day before of her period.After finishing the intercourse I noticed that my sperm was coming out through the bottom of the condom and I was not sure wether it was inserted in her vagina or not..For safety she took a i-pill after 3 hours and after taking pill we had sex again using condom,this time it was protected and no sperm inserted. her period was 6 day late from normal period cycle and now in second month 6 days over still no period. does she get pregnant?If she does,how can we stop having baby? we are not prepared to have baby now
