Doctor didnt order the right blood test?

Sa

Is this normal- I went to the doctors to say my pregnancy tests were positive and to see what the next steps were.

He said I need to get the blood test which I went and got done. I assumed this was to check the HCG levels, but when i checked my copy of the test this isn’t listed, it’s just tests for my iron/ and for my current immunity to diseases including HIV/HEP B etc...

Did he miss something?? Why wouldn’t he get the hcg test?? Did this happen to anyone else? I was 5 weeks when I went to see him so I don’t know why he wouldn’t test for the hcg unless it was an oversight?
