So April 6th I started my period a week early, but I only bleed For one day and my periods are normally three or four days so I took a pregnancy test and I had a faint line. And its been about two weeks since I took that test. Yesterday I took a test and it came back negative. And I am having all the symptoms for early pregnancy. And I have some of the same symptoms I had when I was pregnant with my daughter and she is 6 now. And the app says I should start my period in 5 days and I never had two period in the same month. Any input would be nice
