Hi, I started to show at about 13 weeks and now at 19 + 3 I have a proper big bump - I think I'm expecting an elephant ;-) I'm not very tall, about 5ft 3 and was 11 stone pre-pregnancy - don't know whether this has anything to do with showing quite early? My sister, three years younger than me at 30, is just about to haver her second and with both her pregnancies she's started showing quite late and she's 5ft 6 and about 9.5 stone pre-pregnancy. Just as well I love her or I'd hate her lol. not sure about when people really started to notice - the other week on the traini to work a lady told me that she would have offered me her seat earlier if she'd realisedf I was pregnant, but she thought I was just fat! I felt a bit silly when that made me cry!
