Should I be worried

I know this may be in my head but this is my second pregnancy and my pre-pregnancy weight was 233 I went to my wic appointment it was 226 and today I went to my first doctor appointment and it was 225 I don't know if I should worry or just relax and wait this pregnancy is so much different with nausea and vomiting so early I'm 6 weeks today and I don't want to lose this baby through stressing out
