Thanks for the query.
test kits may not detect early pregnancy.
It may take around one week after missing the expected period to get the accurate result.
So you wait till your expected date of periods and if you miss the period, wait for one more week and go for the test.
The symptoms you are having could be due to early pregnancy or can also be due to some infection.
So you once consult ENT surgeon and get examined for throat pain.
At the time of prescription of drugs mention that you are expecting the pregnancy.
