This may be a miscarriage :( sometimes it doesn't and you can stay pregnant during bleeding but sometimes the body knows it's not forming right so it's trying to start again. You must have barely found out you were pregnant? If it was confirmed by a doctor you need to make an apt and see what's happening. If not, take a test in a week or more and see if you still test positive.
Bright red blood go to the ER!
Had the same problem and as long as you dont need to put on a pad you're okay the bleeding could be caused by UTI but it's best to make sure and go to you're doctor
