Detailed Answer:
HI, thanks for using healthcare magic
Pregnancy tests (both blood and urine tests) detect the HCG hormone . This hormone is produced in increasing amounts as every pregnancy progresses.
It is normally initially detectable by day 11 to 14 after conception especially by blood tests, in some cases it can be detectable earlier.
If your test was done 11 to 14 days after you would have likely conceived then it is likely accurate.
If you are not sure about the time frame then you can repeat it in a few days to get a definite answer especially since you are experiencing symptoms.
Can only be pregnant with negative results if the test was done too early.
I hope this helps, feel free to ask any other questions
 stress can affect hormone levels
Detailed Answer:
HI
Being stressed can affect hormone levels
 generally only a few weeks
Detailed Answer:
HI
Since the HCG hormone levels would be steadily increasing each day if you are pregnant then you can repeat the test in 5 to 7 days to get a definite result.
Stress can generally affect hormone levels at the time, in general this would only last a few weeks (in the majority only 2 to 4) after the end of the stressful interlude
