No. Your uterus has already stretched from the previous pregnancy hence that's why your belly starts to show off early. Your belly will show early too for your subsequent pregnancies. You might also feel your baby's movement (flutters) earlier. Also because you're still in the 1st tri so bloating is very normal at this stage.
Possible, Ako may PCOS ako so normal talaga na may bellyfats. When I got pregant akala nila twins anak ko dahil sa laki ng belly ko.
