Hello morning sickness where are you?

CC28

Today I am 6w/6d and I have yet to throw up once, now and then I get a round of nausea but overall nothing crazy. Is this something other women experience? We have our first Ultra sound on Tuesday - I hope that puts my concerns to rest. I just have had so many friends who had sever morning sickness I’m worried something is not right. I do have VERY sore breasts, pretty sure they already grew half a cup, dizzy now and then, and VERY TIRED, minor cramps now and then but no bleeding. Just feeling thankful that things have been smooth - but also concerned. Anyone having mild symptoms?
