Am I out for the month? 😌

Alice 🇬🇭🇬🇧
I am about 11 DPO today and tested yesterday morning with clear blue digital and got a BFN I don't want to test today and get anothe BFN. I started having period like cramps Monday night and last night they were so bad that I had trouble sleeping and even worse tonight. I still have cramps off and on with barely any CM (normally have right before AF). I normally cramp right before AF (hours before) and then have cramps during for the first day or so. I have never had cramps for almost 3 days with no fluid. Could this be implantation cramps? Am I out this month or is there still a chance? My AF is due Sunday 3th oct.
