bleeding at 5 weeks


Hey everyone , So I found out I was pregnant at 3 weeks. I am 5 weeks and 3 days now but I noticed since yesterday I have been having bleeding. it started out as a small pink specs of blood in my urine and today it continued as Brown spotting with clotting and then tonight I see I have been bleeding lightly and when I wiped it showing as red. I has very light cramping but nothing severe at all. Could this be an ectopic pregnancy ? my first ultrasound is not scheduled until I'm 8 weeks and I don't mind waiting. but if it's ectopic I fear it could be a risk . anyone had issues like this before??
