Ok so October 27 I started my period which was light and isn't normal for me but it ended on November 3. Then starting November 12th through November 15th (about 4 days) where it seemed like a super light period. Too light for even a light days tampon, but it wasn't what spotting would be (pinkish or brown color) it was red. December 30th it started like that again and I still can't wear a tampon normal since there's not enough blood to have one in safely (TSS risk). Also between November 15th and December 30th I did not have a period, but I did take a pregnancy test on December 18th which had the faintest positive line I have ever seen on a test. So am I spotting again or is this just a very late period  or what?
