Has anyone fallen pregnant after only 2 months of having the rebella injection? And was the baby ok?

Hi, I'm a bit worried knowing the doctor had told me not to get pregnant for at least 3 months after having the rebella injection as it is a live virus. 
I'm nurviois to see the doctor next week as I just found out im 2-3 wks pregnant. And it's only been 1-2 months!
​Has anyone else out there had been in this situation and turn out ok in the end?
