Ladies help!!

Hi ladies my husband and I finally got our miracle baby after ttc for 2 years.. currently I'm 5 weeks and 3 days pregnant. Before i had my daughter who is 5 now I had a miscarriage and had to get a D and C. With both of my other kids I was sick alot with morning sickness.My question is should I be concerned at this point?? I have absolutely no morning sickness just really tired.. I'm paranoid and need advice. Thanks
