Bloated 6 weeks pregnancy

Hi, I'm 6 weeks plus now. Finally bfp this time with my 2nd child. Is it normal for my tummy to be big so fast? 1st pregnancy I was fighting with very bad vomiting around this timing till 5mths so I din notice my tummy till almost 5mths. This time round is morning sickness and bloated all day. Nausea and puke in the morning so far. Will bloated makes my tummy to look like 3mths?? Not seeing my gynae until 21 Dec cos that's the earliest date. Thanks all!
