Blood test...

I just went to the doc to have blood test and I told him all my syptoms like : increase appetite, hot flashes, sore nipples, cramps, dizziness even just walking. Anyway he took my temp. And said I have temperature and I might have just caught a bug! A bug?! With those syptoms? Anyway I still insist to have blood test to know once and for all if im pregnant or not. I hate male docs.

Question: do u believe what ur doc says sometimes?
