Some symptoms have gone?

I'm 5w and found out at 4w that we were expecting our first. For my first week I had on and off mild cramps and bloating plus being always hungry and have tender breasts. The cramping and bloating has pretty much stopped and while this should be a good thing it's making me nervous that this could be a sign that something isn't right. Has anyone else experienced the same? We are so excited and nervous and our first doc appointment isn't toll the 31st of March which is sooooo far away!
