Waiting on af...

I'm due to start af tomorrow and so far I have no cramps or back ache (which I always get a couple days before and leading up to af) I haven't taken a test yet because I hate seeing that bfn, I would rather just wait and see if she shows. Do you think this is a good sign with no back pain or cramps or am I being too hopeful? Has anyone experience this and got a bfp? Thanks in advance!!!
