Bleeding after BFP

Kelsey
So I got a vvfl on multiple HPTs yesterday and today. Just went to the bathroom and had bright red blood when I wiped. I had a chemical last month but it didn't happen until 10 days after I got my positive last time. 
Has anyone had bright red bleeding so early (app says I'm 3+4) and had a successful pregnancy? My heart is breaking thinking I'm having another chemical...
