seeing blood freaking out


I'm 5 weeks today, have regular pregnancy syptoms, nausea, hot flashes, smells turning my stomach, insomnia. had period like cramps this afternoon everyone said it's normal pregnancy. then I just went to the bathroom 15 minutes ago sorry tmi had a bowel movement and pee. wiped my behind and there was some bright blood each time I wiped. then I wiped my front and there was a dot of blood like a pin dot. looked like there was blood in the toilet but I have no idea how much since I went poop. I'm freaking out that I'm having a miscarriage or something. I don't have my ultrasound til the 10th. anyone have this ever before?
