Bleeding after positive pregnancy test

I took a test on 9 dpo and got a faint line on a blue lined test, so I got a first response and took it at night at 10 dpo and it was a super faint line. This morning on 11 dpo I took a test and it looked a little bit lighter than it was the night before which I thought was strange but I wasn't giving up hope. Now during the middle of the day on 11dpo I started bleeding. It's not heavy but it's been consistent all day. Not enough to make it on my pad but every time I wipe it's there. Is this the start of a miscarriage? Or has anybody had anything similar happen to them? I know I just have to wait it out to find out but just looking for some in site from others!
