The correct answer is taking the test too early in the pregnancy.
A pregnancy test is a device used to test your blood or urine in order to determine whether you are pregnant or not. A pregnancy test works by detecting specific markers in your urine or blood. One of the most common marker used is human chorionic gonadotropin (hCG), a hormone produced after the implantation of the fertilized egg on the uterus. This hormone is detectable in the urine only 10 days after the fertilization of the egg, meaning that if a woman takes the pregnancy test too early it may have a false negative result.
Low blood pressure on the other hand can be to do with:
Exercise and how much you do of it because regular exercise keeps blood pressure low.
Eating as after you eat, blood pressure falls.<span><span>
Stress causes blood pressure to rise.
Body temperature and how high it is affects BP because if you're body temperature is high, your BP is usually low.
Hope that helps.
