My girlfriend and i had sex and we use a condom and i cum in it will she get pregnant?

Condom Concepts: Condoms are used to prevent pregnancy by blocking sperm from getting into the woman's vagina. Ejaculation usually occurs while the covered penis is still within the vagina. It is important to remove the condom before the penis gets soft, as leakage or slippage can occur. While condoms can break, this is not a common event. Additionally, condoms can prevent many stds.
