Ok so this is my first pregnancy and going by my last period I'm 6 weeks 4 days right now I'm not skinny but not really super fat and when laying down my tummy used to be fat and now it's not. Top picture 4 weeks 5 days middle picture 5 weeks 4 days and bottom tonight 6 weeks 4 days what do you think?
