When did people start showing with their third? I am reading stories of people showing in the first trimester but I just don't think that is physiologically possible is it? As when you 'show' it is because the top of the uterus has started to come up over the pelvic bone and as the fundus ( top of the uterus) can't be felt by medical staff until the 12 week mark it can't be possible to show until around then. No matter if it's your 1st or 10th pregnancy that won't change. I didn't show for DD until about 6 months and was in normal clothes until 8 months and DS about 5 months. This time round I know my muscle tone is non-existent so I am pretty sure as soon as that fundus comes over there will be nothing much holding in!! I like to think I am showing now ( 8 weeks) but really I know it is just bloating which - if I was not pregnant I would consider myself to be having a fat day and would look exactly the same -LOL.
