The work done on a system is positive when energy is added to the system, and negative when energy is removed from the system.
False positive pregnancy tests are VERY RARE! False negatives are more common, especially when the test is done too soon after conception. If you have a negative pregnancy test and don't start your period redo the test in 3 days.
Work done by the system is considered as PositiveWork done on the system is considered as Negative
they check baby and mother to see whats going on and if anything needs to be done
It's VERY rare to get a false pregnancy test, if you are concerened, you could have a test done with a doctor or a family planning clinic, but I would say that you are indeed pregnant ~pawsalmighty
Yes as they are negative you can conclude, the test is negative and nothing to worry.
Positive forces can counter negative forces.
Subtracting a negative is like adding a positive.
When you miscarry it takes a few weeks until the hormones settle. During that time the tests will show pregnant. The bests tests are done at the clinic and they can also take a ultrasound to make sure.
