Hi,
Thanks for the query.
Usually
blood test will get accurate result when compared with urine tests.
Sometimes urine test can give false positives.
But as both your urine test reports were postie, you better go for
ultrasound once.
As it is almost 45days from your last menstrual periods, in case of presence of pregnancy, the
gestational sac along with
fetal pole can be visualized.
If ultrasound shows absence of sac, you can take tablets for withdrawal bleeding with your doctor's advice.
Take care.
