Is this normal?

My husband and I have been trying to conceive. My period is due in a couple of days, however some things have been happening that have never happened before. My cervix has dropped really low (which has never occurred). I have a very high cervix. He bottomed out, yesterday was the first time he’s ever done that, and I’ve been cramping. I never cramp until the later part of my period. Could this be a sign?
