I need some experienced moms opinions pls!

Okay so this will be my 4th pregnancy I have 2 lil boys only 15 months apart they are 2 and 1 yrs old but I got pregnant when my youngest was 6 months but miscarried when he was 9 months in August so I was 12 wks well my oh has said that since I haven’t let my body go back to “normal” before I get pregnant I tend to show earlier then normal. So I am currently 5 wks and I just feel extremely big already.
