I'm 29 weeks and 3 days with twins and didn't really start showing until maybe 24 weeks. So it is different for each woman and body type. Yes having twins is overwhelming but exciting too. We knew from the dating scan (first vaginal ultrasound ) there was two distinct sacs.
I'm having twins I'm 9 weeks and definitely look pregnant I can't keep it quiet for much longer I'm a hairdresser and all my clients keep hinting and asking questions. All my clothes are too tight already too. It was a complete shock but a lovely feeling. Everyone is different people bloat/hold more water than others or there could be 2. A sign for me was In early stages i got pregnancy cramps and had a stitch feeling on both sides of my belly I knew then there were 2 as I didn't have that in my first.
I have a pretty small frame, my waist has only expanded about two inches since I've been pregnant and I'm 24 weeks. So people are always talking about how huge I am but I think it's just the ratio of belly to waist lol.
I've noticed people say that to almost every pregnant girl lol. Especially if you were small first. I wouldn't take it to heart either way.
