If people had to absolutely know for sure before the woman shows signs, they would inject rabbits and rats with the woman's urine. If the animal goes into heat, then she is pregnant. Rabbits usually died anyway from the urine injections, and they used to use a phrase 'the rabbit died' to inform people they were pregnant.
But most of the time, women were just patient to wait and see; the periods stop, belly/hips getting bigger, morning sickness.... the basic signs are the indicator that was used for centuries.
A doctor's pregnancy test is much more accurate, where as a home pregnancy test can be faulty.

It depends on what that pregnancy test uses to indicate pregnancy. Read the directions carefully to see what they use to indicate a positive or negative pregnancy test.

If the pregnancy test was negative, it means that you are not pregnant.
No, a fertility test tells you if you are capable of conception or when your best time to conceive is. A pregnancy test tells if the pregnancy hormone is present in your urine.
A serum pregnancy test is a type of blood test that measures the level of human chorionic gonadotropin (hCG) in the blood to detect pregnancy. It is considered more accurate than urine pregnancy tests and can detect pregnancy earlier.
