Bfp straight after chemical pregnancy

I had a chemical last month. Got my bfp at 10dpo but it fluctuated over the next few days and at 15dpo I started bleeding heavily. I got a negative test after this. I have just got another bfp without a normal period inbetween and I'm petrified to get excited. Got my bfp at 9dpo and I'm now 11dpo. Does this line profession /darkness look okay for 9-11dpo? I'm not due on until Sunday. Thank u so much.. Scared mama here x
