Day after fertile window

So this is my first month off birth control so my body might be adjusting a little, but I defiantly feel different. I just ended my fertile window yesterday 3/3, but my husband and I haven't had sex since Sunday. I have been bloated the past 24 hours and craving salt like a crazy person (I can't get enough.) I have been cramping on and off today. I  normally have a little bloating a few days before my period and crave sweets. AF shouldn't start until March 14. What are your thoughts? Body changing. Might be pregnant.
