Could I be pregnant?

I'm just curious and need opinions on if I could be pregnant or if I am experiencing the beginning of pregnancy symptoms? I'm 9 days out from AF and 2 days post my ovulation window. Since Saturday or Friday I've had low back pain and little cramping and boobs are a little sore like they are before my period and a lot of watery clear discharge. Is this just part of ovulation? Kind of just curious and wondering.
