Confused???

Im 10 days late, and ive took multiple test and they are all comimg back neg. Went to the doc today and they did a pee test, and it said neg also. The doc told me a blood test would most likely come out neg to so i shouldnt waste my time. Im pretty regular since i got my IUD out a little over 9 months ago. Im so overwhelmed, and just being told to be patient and chill dont help any. Ugh, what do y'all think?
