9 dpo, bfn but cravings

Louise
I hate bacon, have not eaten it for about 20 years, the smell, taste, texture absolutely turns my stomach. Until yesterday! I started craving it it. Today I gave in and ate 8 rashers!!! 
Had some cramps a few days ago and felt tired all week but no other symptoms. 
Bbt has been 0.4 degrees c elivated for past 3 days also. 
Clutching at straws?
