9wks and sluggish!

So I'm 9wks and 4days and I feel pregnant. Like my belly is bigger than last nights, and I think it's bloat because I don't think I'd be showing that much but it like so much. I feel really tired and sluggish, it's uncomfortable bending over, and now I can finally fit the maternity pants I brought. Part of me is really happy and the other part is just like, "It's just a lot of bloat." This is my first pregnancy, so I don't know how much I should be showing and when.
