TTC #2 HELP so confused

DREAMING about that big family!

Normally my luteal phase is 8-10dpo. I’m 11 dpo today with no AF and a BFN. With my first pregnancy I had a BFN on 11 dpo and started bleeding and got a BFP on 14 dpo when the bleeding stopped. Could that be what’s going on now?

*Edit to ask if you implant later one pregnancy do you typically always implant later?
