i know exactly how you feel!!! i'm supposed to get AF tomorrow!!! i usually have cramps, but i dont have any! i feel like im gonna throw up all day today but i have this tiny part of me that is scared shes coming tomorrow.
This happened to me...I took test upon test with no BFP...I went to the hospital for my asthma..and when I took the pg test it was very faint..when they took my blood..it confirmed I was pregnant..So it may happen Keep the faith..
