MMR 2-3 weeks ago

Hi everyone, i am posting this on behalf of my friend, she got an MMR jab aboit 2-3 weeks ago. An she has just found out she is pregant. She's really scared beacuse she has read online that you are not allowed to get pregant within a month of having the jab as it can course really bad problems for the baby. an she will have to get rid of it. is this true? any help or advice will be great
