Help...

Okay you guys I need some help! The past two weeks have been wierd...my breastfeeding have been more sensitive, been having pain left side where cramping usually happens at, and some food smells make my stomach turn. I had my period the 4th of this month and shouldn't have it till next month on the 4th. People have been telling me that they have had dreams of me being pregnant and have told me I am pregnant. I just want to know yalls point on this. Could I be or what's happening...
