Pregnancy sickness maybe?

I just hit the 6 week mark and I have been feeling a little nauseated amd crampa, I have no bleeding. At 5 weeks my symptoms stopped but I had frequent urination and cravings. Last night I felt so nauseated and I woke up this morning still feeling nauseated. Is thia normal? I also feel slight cramps but the nauseated symptom is really strong. I ate yesterday and took my vitamins but walked a little more than usual. I dont know if its morning/night sickness or what, this is my first pregnancy. I camt wven fall asleep because I feel sick. Opinions? (my hubby felt nauseated last night as well)
