Nausea during Pregnancy

So I'm on baby #2. 6.5 weeks pregnant. With my son, I didnt get morning sickness or nausea until my 2nd trimester. With this baby, I am getting nauseous like everyday and some days it's hard to get out of bed without getting sick. I know every pregnancy is different but should I be worried at all that I'm getting more nausea this time around?
