Still no drunks - but, the weekend starts today and my shift ends at 2am...

I'm going to describe a job I went to last night.

The patient is female and 30 years old. She is married and is attempting to get pregnant. She is currently only taking fertility treatment, and having unprotected sex - she is normally fit and healthy and has no allergies. Her normal menstrual period is regular, however her period is over two weeks late this time around. She has been having nausea and vomiting for the past three days. She has no abdominal pain, and is not tender or guarding. She has no pain or increased frequency of passing urine. All vital signs are within normal limits.

So - given this information...

a) What do you think is 'wrong' with her?

b) Does she need a trip to hospital in an ambulance?

c) Why do you think she hasn't done a pregnancy test?
