A weakly positive ovulation test after 10 days of intercourse does not mean that you are not pregnant. Ovulation test paper measures luteinizing hormone, which can accurately detect whether there is ovulation or not, but it does not check if you are actually pregnant. Because this is not sensitive to side pregnancy, you need to use early pregnancy test paper to detect whether you are pregnant, 10 days is relatively early, you can take a blood test to determine HCG, which is a more accurate indicator of pregnancy, if the test result is positive, it is sure to be pregnant, if the test is negative, you still need to take a blood test after 1 week, so that you can determine down whether you are pregnant.
