2 days late bfn

I'm 13dpo period was due Sunday still no sign of her. Normally I spot the day before. I spotted 7dp o-11dp o only a little bit each morning. I was thinking that was implantation but now I'm not so sure. Also, my boobs don't get sore before af and since 11dp o they have been sore. I'm so confused with all the bfn and the absence of af. I tested + on the 17th so I know mi at least ovulated. Is there still hope for a bfp??
