Pregnant friend doesnt know how far along she is

Patient: Hi there my name is lynn clydesdale, my friend told me today that she took a pregnancy test on jan 3 and it told her that she was 1-2 weeks pregnant. However, she doesn’t know how far along she is now, and she really wants to know. I asked when her last period was and she said she never got one just her 6 week preiod after she had her son. Would you be able to tell me how far along she is? Thank you
