Is this normal?

When I was pregnant last March, I had literally no symptoms other than sore boobs, sadly miscarried at 13 weeks tho :( now I'm pregnant again, about 5 weeks 4 days and I have sore boobs and super gassy and tired and get hiccups a lot, but no morning sickness.. is it too early? Or do some people just really not get sick? I almost wish I did so that I knew everything was ok!
