Home pregnancy tests are urine tests that check if there is human chorionic gonadotropin hormone (HCG) present in the urine. If there is, it usually means you are pregnant.
HCG Strips
The most basic type of pregnancy test is a simple strip of paper that you dip into a sample of urine. The strip of paper then changes color if you are pregnant. Some HCG strips have a one line result if you aren’t pregnant and a two line result if you are. These types of tests are the cheapest available and you can buy them in bulk packs from online pharmacies for as little as a few cents each. If you are on a budget this is an ideal option.
