Generally speaking, sisters can perform self-tests 7-10 days after the couple has sex. They can test pregnancy by using early pregnancy test strips or pregnancy test sticks to test morning urine. The longer the time after sex, the more accurate the results will be. Generally speaking, you can find out whether you are pregnant in one week at the earliest and about 3 weeks at the latest! Usually in the early stages of pregnancy, many sisters will experience a series of early pregnancy reactions such as dizziness, nausea, drowsiness, and breast swelling. Generally, these symptoms will become more obvious 10-14 days after pregnancy, and will disappear on their own after three months. Therefore, if you have the above symptoms but are not sure whether you are pregnant, you can use early pregnancy test paper and pregnancy test stick to test pregnancy. I wish my sisters a good pregnancy!
