59days late???😕

Hey lm just after some feedback please anybody. lm 59days late, the last month my breast have doubled in size and starting to ache, l have a bit of an evasion to some foods and nausea...l seem to be getting all the postive signs of being preggas but heres the catch...l went to the Dr's and he gave me urine test that came up postive followed by another 4 faint liners test that l brought from the chemist anyway...that was 2 weeks ago. I followed this up with a blood test that came back negative...couldn't believe it so decided to do a follow up urine test a couple of days later now the line is even darker.Now heres the kicker l'm in remission with graves disease, which took years to even diagnose, prior l was undiagnosed with hypothyroidism then hasimotos followed by hyperthyroidism. So my concern is if say l've gone into any of these thyroid conditions again would l get a proper read on a blood test???. I know that there accurate but the urine test line was even darker after the blood test!...at the mo lm waiting for my endocrinologist to call me back, so l can discuss what's the go with all this...any feedback would be great because l'm sorry worried 😕and my fingers are crossed that the follow up urine test is a blessing...😌
