Anyone experiencing symptoms but not pregnant?

Hi all.

So my AF is due today and I still don't have any signs she is coming. I have woken up everyday for the last week nauseated (violently vomiting one of them). My breasts hurt especially my one of my nipples (totally weird). I have a headache which won't go away with paracetamol. I didn't have these symptoms with my first two. Does anyone else suffer with symptoms like this when AF is due?

I am not sure if it is to early to have these signs!!!
