When Will I Get My Periods After Delivery?

I just gave birth to my daughter on September 17, 2010. I breast fed her until 2 weeks ago. She is 4 1/2 months old now. How soon can I expect to have my period. I am not breast feeding at all now. Also I have had the hiccups randomly since my daughter was born. Plus I have been having this fluttering feeling in my stomach, kind of like when I was pregnant. Does that mean I am again?
