Hi If I Possibly Conceived Nov 4 (date I Had

Hi if I possibly conceived Nov 4 (date I had sex) and I took a pr3gnancy test Monday night Nov 14 is it possible it was a false negative. My period was due Nov 9 and it still hasn't shown up it is now Nov 17 it's 8 days late which has never happened. When would a blood pregnancy test be recommended or a urine test recommended for accurate results. As well after implantation ends does your hcg level rise from 1 to 5 immediately or increase by doubling every 48 hours, for example 1 then 48 hours later 2 48 hours 4 etc until late it reaches a lvl a test can pick up on
