Hi my name is Brooke and I am 21 years old. I started spotting yesterday and it s was bright red and thin this morning with no clots. But then it just stopped. There is no trace of the bleeding whatsoever. It is 12 days before my expected start date and I was wondering if it could be implantation bleeding even though it was bright red this morning. It was only bright red that one time going to the restroom. All other times were brown or light pink. Again very thin with no clots.
