Yes it can but this does not mean you are pregnant. After ten minutes you should get rid of the test because after 10 mins the result is not correct. It should state this on the instruction pack and how long you should read the test before throwing it away.
The best thing to do is see your doctor

Compound having any positive or negative particle are said to be charged particle . it is not so that there should be same number of positive or negative infact these are called saturated particle .an atom carring positive particle are called cationwhile negative particle are called anionby MK
An object with equal amounts of positive and negative charge is electrically neutral.
the unlike charges are those which attract each other
well the difference between positive and negative velocity would have to be that if your motion speeds up than you have a positive and when or if your motion slows down then you would have a negative accelerarion!!!!
If the atoms have opposite charges (positive to negative) they will attract. If the atoms have the same charges (positive to positive or negative to negative) then they will repel. You can look at the Law of Electric Charges to get more information on this.
