Earliest sign of pregnancy

Hello everyone. I stopped taking pills early this month and got my period from the 11th-16th. I've been having "pregnancy symptoms" but I know it's way too early for it. I've been feeling bloated, breasts are feeling quite heavy and sore, discomfort on the left side of my back, and nauseous. My husband is laughing at me cuz he thinks it's way too early and I'm just feeling this way cuz I stopped my pills and really wanting to conceive right away... 
Anyone had experienced this?! 
Thank you...
