When girls get their periods is it normal to a really dark red gushy thing?

Yes, it is normal to have a dark red gushy discharge when you first start your period. This is because the menstrual blood is mixed with mucus and tissue from the lining of the uterus. The color of the blood can vary from light pink to dark brown, and the flow can be heavy or light. It is also common for girls to experience cramps, headaches, and mood swings around the time of their period. If you are concerned about your period, talk to your doctor or other trusted adult.
