Likelihood of 2 chemical pregnancies back to back?

Hey all, is there a pretty high chance of one having 2 chemicals back to back? I had a chemical pregnancy last cycle. This cycle I have been feeling off, so I took a test (at 8dpo) thinking it would be negative because it is early, and got a faint (but able to see a line without squinting or manipulating) line on a test today. Do you think there is a high chance that it could be another chemical pregnancy or that it is actually a successful pregnancy? I am still four days from expected AF. Any advice would be appreciated, just freaking out, don’t want to get excited for it just be brought down again! TIA!
