I have a GP who is supportive of alternative therapies and has even suggested non 'medical' options at times. She also admits she's not an expert at fertility but supports my efforts. So if I want a blood test for X, y or z she fills out the path slip. Not all GPs are like yours. It's still just her opinion. I get bloodtests to measure things before trying alt therapies. Did you get the path slips? If not, try another doctor.
