The difference between the cheap and expensive pregnancy test is that the expensive pregnancy test has better packaging and a concave area will appear directly on the side of the pregnancy test, so if you put a drop of medicine directly into the concave area, you will know whether you are pregnant or not through observation. The cheaper pregnancy test requires inserting one end of the stick into the urine for a few seconds and then taking it out and laying it flat to see if you are pregnant or not, so one is relatively easier and the other is relatively more troublesome, but clinically there is no difference in the results. It is also recommended that if you use a pregnancy test around 35 days after menopause, it is best to keep the morning urine for testing because the HCG level in the morning urine is relatively higher.
