Trying to conceive for 1 year you have had 3 days of brown spotting when my period was due took home pregnancy test yesterday it negative any chance could be wrong?

It is possible that the home pregnancy test was wrong, especially if it was taken very early. It is recommended to wait at least one week after your missed period to take a home pregnancy test for the most accurate results. Brown spotting can be a sign of implantation, which is when the fertilized egg attaches to the lining of the uterus. However, it can also be a sign of other conditions, such as hormonal imbalances or uterine abnormalities. If you are still concerned about whether or not you are pregnant, it is best to see a doctor for a blood test, which can detect pregnancy earlier than a home pregnancy test.
