Chemical pregnancy? Or true BFP?

Kelly

First picture is day 1 of my supposed period, Saturday the 16th. Second is Sunday the 17th and digital is today, Monday the 18th. I am 3 days late as of today. I believe I am 15 dpo. Could these be showing a chemical pregnancy or a real pregnancy?? The earliest appt with my Ob/Gyn is Oct 3rd. So I have to wait until then for a blood test. Thank you all in advance!
