Bleeding

So I feel like I'm pregnant. My breasts have been pretty tender for about a week. I have taken a few hpt and only one has had a faint positive the rest have all been bfn. I started to spot on Sunday 8/14 wasn't due for period until 8/16. I have had pink/red/brown blood not heavy at all and nothing like my normal periods. I don't know what to do. I had a miscarriage in June and I'm really hoping it will be my turn for a bfp.
