You CAN NOT base a singleton pregnancy and a multiples pregnancy on how early you show. The only way you will know is to get an u/s done.
Having twins doesnt neccesarily mean you will start showing any sooner than normal. I am 11 weeks along with twins and I dont look any different than my last pregnancy at this point. Things are so small right now that it wouldnt show on the outside. The only way to know if your having twins is by confirmation by an u/s. I also agree with natasha and think that once you have already given birth, your skin is already stretched from the last time and you do start showing sooner than someone on their first pregnancy. Good luck and congrats on your pregnancy!
hello darling, if you look on my post thing there's a pikkie of me, i look 6 months gone, just come back from scan only 1 in there, apparently after a 1st pg you're body knows what going on and just pooches out (thats the word they used) almost immediatly after you do a test, so altho the chances for all of us are good, actually it may just be like me and your body knows its got to grow and just gets on with it, congrats and good luck xx
