I just recently started back taking my birth control pill the beginning of April. I had a period last month but I didn't have one this month. Yesterday I was spotting it was a light pinkish color and didn't last very long. I took a test 4 days ago. When I took the test it showed nothing. I forgot I had the test so yesterday as I was about to throw it away I seen a positive sign but the line was barely even there it was faded. Again, I went to walmart to get a different test it showed positive again and the line was darker than the last test I took but it was still faded.....
