I am having a light brown discharge on my tissue when wipe and have not had period this month. always start the 20th of could be pregnant but sure. Any advice?

It's possible that the light brown discharge you're experiencing could be a sign of early pregnancy, as implantation bleeding can occur around the time of your expected period. However, it's also important to consider other possible causes, such as hormonal imbalances, stress, or an infection. To determine the cause of the discharge and whether you're pregnant, it's best to take a pregnancy test. If the test is negative and the discharge persists or becomes heavier, it's important to see a doctor to rule out any underlying medical conditions.
