Pain on left side?

My OBGYN appointment is almost here (Monday).
My last period was May 29th. I've taken hpt, one faint and 4 negative!? I'm cramping like AF is coming but never comes! Usually my boobs hurt and I break out when AF is about to show. And NOTHING. I'm just bloated, hungry all the time, and a strange pain on left side? Anyone else ever go through this? Monday needs to be here already!
