I may not be having a chemical like I thought. I woke up at 5 AM and decided to test with FMU. When I wiped there was brown blood, quite a bit. I wasn't too concerned but then I had red blood and panicked since AF would have been due today. Cried hysterically until I fell asleep. Woke up and no blood at all now... didn't bleed after that bit this morning. Now it's just a waiting game until I can see my OB tomorrow.
