I am pregnant. I just went to the bathroom and a grayish clot came out. It contain a little blood and it is kind of firm. I am not bleeding or cramping. Should I be worried? Is this a sign of a miscarriage?

If your body is doing something that is not normal for you, especially excessive bleeding or clotting, then you should always contact your doctor to be sure it isn't anything more serious. Pregnancy makes women's bodies go through all sorts of different things, and every woman is different, so you should just have it checked to be sure. Good luck!
