What should I expect?

Hey Glow Gang! I know everyone's body is different and no one has the same pregnancy experience, but my husband and I have been ttc for about four months now. I'm curious. When you are waiting around in those moments for your period to  start (hopefully not though). Do most women still experience pre-menstral like cramping? I'm supposed to start on the 4th, and already cramping. My hopes for being pregnant this month are getting low because of the cramping pains. PLEASE HELP.
