I have a girl friend.we already had sex for 3times.can i give her an i-pill after sex and again doing sex and can again give i-pill? will it work

Her decision: Using the morning after pill as birth control is not recommended. She is likely to have very irregular bleeding. But if she is not on birth control and it has been less than 5 days, she can take the morning after pill. You should be using condoms. She needs to see her gynecologist for a longer term bc. But you should not stop using condoms as the pill can fail. And then you are a dad.
