What pregnancy symptoms should I be experiencing at 5 weeks?

Hello everyone! Well I am currently 5weeks and 4 days pregnant but I was wondering what symptoms I should be experiencing. Ever since a few days after I missed my period I have had morning and strong motion sickness and even thrown up. My boobs and nipples are hurting so bad it hurts even when I sleep. I had never been so dehydrated in my life I drink so much water now and pee a million times a day. I feel as if my ribs are being ripped open from the inside and I have had a lot of slight cramping but not painful just I feel things happening down there. I have no blood though. I also have a lot of white creamy odorless discharge. I was wondering if all these symptoms are normal. I have spoken with many people that have had children and they told me my symptoms are quite strong for being so early. Is this going to get worse? Is this normal?
