Quoting Mama BooBoo(::" dang im sorry! that sounds aweful. are you on any type of birth control? sometimes that can cause blood clots!"
Quoting I AM TRON:" Is it possible that you are having a miscarriage? Not that you can really do anything to change it, but from what you are describing that is what it sounds like. =\"
Quoting Brandy&TayTay:" i took test but they all said negative. But if i were miscarrying idk if it would show up."Very possible, especially if it were a missed M/C. I know a lot of women who don't even get BFPs till 15-20 DPO. I would definitely get into a doctor though. Something doesn't sound right.
