PLEASE HELP? LOW AND VERY OPEN CERVIX

I had my daughter 3 months ago and still haven't started my period :( I've been cramping for like 2 weeks and I wish my period would start. I'm not on birth control and I'm only breast feeding a couple/few times a day. anyway I just checked and my cervix is low enough to easily feel and it's really open like i could put a finger inside.. What is low and open cervix mean? anyone know? And anyone know how I could maybe start my period with a remedy at home? thank u
