Clinging to hope but i think I'm losing my baby

Everything has been great this pregnancy and i found myself feeling optimistic and confident that everything would go well and that i would meet my baby in december. But today at 7w1d i started bleeding. I'm going in at 1:30 for a scan but i know it's not looking good. Bleeding (with small clots) started out of nowhere and im not cramping but i cant imagine this ends any other way besides miscarriage. I'm heartbroken... update: everything is okay! Yall were right and it's a sch. Thanks for all your kind words!
