Frer pink wrapper

I took one this morning and bfn. I'm 9 dpo and used FMU. Am I out. How many have gotten negative befor positives early. Some data states that they detect 6 of hcg vs the normal 25.  If I'm probably out I would just like to know. I see many people get bfp at or before 9 dpo. If you have gotten negatives at 9dpo only to go on to bfp it would be appreciated. Thanks
